Maximizing Collaboration: Microsoft Teams Guest Access Guide

By inviting external partners, freelancers, and clients into your Microsoft Teams environment through guest access, your organization opens the door to seamless, productive partnerships. Learn how to best navigate guest access here.

Known for its robust messaging, video conferencing, and productivity apps, Microsoft Teams has quickly become integral to modern business workflows. In fact, the popularity of Teams is so significant that it secured the third rank with 111 million global downloads in 2022 among leading business apps worldwide, and 43% of Americans recognize the Microsoft Teams brand by its logo.

An integral feature of Microsoft Teams that enhances its collaborative prowess is guest access. This functionality allows organizations to invite external users, such as partners, clients, or freelancers, to join their Teams environment, providing a seamless avenue for collaboration outside the conventional organizational boundaries. Guest access is distinct from external access (the latter being the topic of a separate piece), which is more about federated relationships between different organizations. Unlike external access, which allows users to see presence, send messages, and make calls, guest access integrates external users more deeply into the team’s workspace, allowing them to participate fully in projects, access files, and join meetings.

With extensive expertise building applications for Microsoft across a wide range of enterprises, VirtoSoftware deeply understands the transformational impact guest access can have. We have enabled thousands of external collaborations, seeing directly how this functionality strengthens organizational alignment and productivity when thoughtfully adopted. Our expertise in creating collaborative solutions gives us a unique vantage point from which to guide you through setting up guest access, effectively managing and revoking these privileges, and ensuring that collaboration with guests remains secure and productive.  

By the end of this guide, you will be equipped with the knowledge to enhance your collaborative efforts using Microsoft Teams Guest Access, ensuring that your interactions with external users are as streamlined and effective as those within your organization. 

Understanding Microsoft Teams Guest Access

As mentioned, a pivotal feature supporting cross-organizational collaboration in Microsoft Teams is guest access.

So, what is Microsoft Teams guest access? Guest access in Microsoft Teams allows individuals outside your organization to be added to your teams, where they can participate almost as if they were one of your own employees. This means that once added, guests can join meetings, collaborate on documents, and engage in chat conversations within specific teams.

This feature is particularly useful for projects that involve external contractors, consultants, or partners who need to work closely with your team for a defined period. By integrating these external users into your Teams environment, you create a unified space for shared work, regardless of organizational boundaries.

👉 So, does Microsoft Teams allow guest access? Yes, indeed, it does. As discussed, organizations can invite external users to participate as guests in Microsoft Teams activities. Guests can join meetings, collaborate on documents, and participate in chats and channels, provided the guest access feature is enabled and appropriately configured in the Teams admin center.

How does guest access work?

When you enable Guest access in Microsoft Teams, you essentially grant external users access to select resources within your Teams environment. These guests are not part of your organization’s official directory but are invited individually by authorized members of your teams via their email addresses. Once added, they have specific permissions that control what they can and cannot do within the team settings.

Levels of guest access permissions

Guest access is not a one-size-fits-all setting; it involves various levels of permissions that can be tailored according to the need for security and the nature of collaboration. For example, you might allow a guest to participate in meetings and view documents but restrict their ability to upload new files or create new channels. These permissions ensure that guests have enough access to collaborate effectively while safeguarding your organization’s data and internal communications.

The different levels of guest access permissions are crucial for maintaining control over your digital workspace and will be discussed in more detail later in this article. 

Typical Use Cases of Using Guest Access for Microsoft Teams

Guest access in Microsoft Teams is a versatile feature extensively used by a diverse range of users and organizations. It caters to various scenarios where collaboration with individuals outside of a team’s primary members is essential. Below, we explore some typical use cases of guest access, highlighting how different sectors and teams can leverage this feature to enhance their collaborative efforts.

  1. Cooperation with external partners

Organizations frequently engage with external partners for joint ventures, product development, or market expansion. Guest access in Microsoft Teams facilitates these partnerships by allowing external partners to join specific teams. This inclusion enables partners to participate actively in discussions, access relevant documents, and contribute to shared projects, all within a controlled environment. For instance, a software development company could use guest access to collaborate with a design firm on a new app, providing a seamless platform for exchanging ideas and tracking progress.

  1. Communication with clients

Maintaining open lines of communication with clients is crucial for businesses aiming to deliver exceptional service. Through guest access, clients can be added to relevant teams where they can directly communicate with project managers, provide feedback, and monitor project milestones. This direct involvement helps in building trust and ensuring client satisfaction by making the communication process transparent and interactive. For example, a marketing agency might use Teams to share campaign progress with a client, allowing for real-time feedback and adjustments.

  1. Holding events

Organizing webinars, workshops, or virtual conferences often involves participants from various backgrounds and locations. Guest access allows event organizers to create specific Teams channels for these events, inviting speakers, attendees, and stakeholders to join. This setup facilitates the distribution of event materials, scheduling updates, and post-event discussions in a single, accessible platform. It enhances participant engagement and streamlines the management of event-related communications.

  1. Temporary cooperation

Projects often require temporary staff or consultants who need access to company resources for a limited period. Guest access is ideal in these situations, as it allows these temporary team members to collaborate effectively without compromising the security of the organization’s internal communications. Once the project is complete, their access can be easily revoked, ensuring that only current team members have continued access. This is particularly useful in industries like construction or film production, where many temporary contractors may need to come together quickly and efficiently.

  1. Knowledge sharing

Educational workshops, training sessions, or industry-specific discussions benefit significantly from guest access. Experts or trainers from outside the organization can be invited to Teams where they can share their knowledge, interact with employees, and provide valuable insights. This setup not only facilitates robust knowledge transfer but also allows for recording these sessions for future reference, enhancing the learning experience.

In each of these use cases, guest access in Microsoft Teams proves to be a critical tool for enhancing collaboration, ensuring that all parties involved are equipped with the necessary tools and information to contribute effectively to shared goals. By understanding and using this feature, organizations can significantly improve their interactions with non-team members, leading to more successful collaborations and outcomes.

Enable or Disable Guest Access Microsoft Teams

Properly managing guest access in Microsoft Teams is crucial for maintaining both flexibility in collaboration and security within your digital workspace. This guide provides detailed instructions for IT administrators on how to enable or disable guest access, along with the implications of these settings.

👉 How to restrict guest access in Microsoft Teams? To restrict or disable guest access, you’ll need to follow the same steps as above. Go to the Microsoft Teams admin center—this is where you’ll find Microsoft Teams guest access settings. Then, ‘Org-wide settings’ > ‘Guest access.’ Adjust the toggles for activities guests can and cannot do, such as making private calls, adding or removing apps, and more. 

NB! Enabling guest access opens up avenues for external collaboration but also introduces potential risks. It is essential to carefully configure guest permissions to ensure that sensitive information remains protected. Consider limiting certain privileges such as file sharing and access to organizational data unless absolutely necessary. Regularly review and update these settings to align with current security policies and collaboration needs.

👉 Learn more about enabling/disabling and configuring guest access in the Microsoft official documentation: Turn guest access in Microsoft Teams on or off.

For team owners: Managing guest access at the team level

While IT administrators control whether guest access is enabled or disabled on a broad level, team owners have specific responsibilities for managing guest access within their individual teams.

Managing guest access, therefore, comes down to:

  • Adding guests: Team owners can add guests by going to the team in Microsoft Teams, clicking on ‘…’ (more options), and selecting ‘Add member’. Enter the guest’s email address, and they will be invited to join the team.
  • Removing guests: To remove a guest, navigate to the team’s member list, find the guest you wish to remove, click on their name, and select ‘Remove from team’.

For detailed instructions on adding/removing guest users, please see the later section in this article, ‘Add Guests to a Team in Microsoft Teams’.

 👉Why is Microsoft Teams guest access not working? If guest access isn’t working, it could be due to several reasons, such as the guest access feature being disabled, specific policy settings, or licensing issues. Sometimes, changes in settings might take some time (up to 24 hours) to propagate. So check access later, and if it’s still not working, contact your admin.

NB! It is important for team owners to regularly review who has access to their team, ensuring that only the necessary individuals have guest permissions. This practice helps maintain the security and integrity of the team’s collaborative environment.

👉 For further information on managing guest access in Microsoft Teams, refer to Microsoft’s official guide: Guest access in Microsoft Teams.

Microsoft Teams Guest Access Experience

When external collaborators are added to Microsoft Teams via guest access, they gain the ability to participate in specific team activities almost as if they were internal team members. Understanding the extent of what guests can do and how they are identified within Teams helps both guests and team members navigate the collaboration environment effectively. This section covers the key capabilities and experiences guest users have within Teams to support this effective cross-organizational engagement.

Features and functionality available to guests

Guests in Microsoft Teams enjoy a range of functionalities that facilitate effective collaboration across organizational boundaries. Here are some of the key features available to guests:

  • Participation in channels: Guests can participate in conversations in channels, respond to posts, and use @mentions to draw attention.
  • Meetings and calls: Guests have the ability to join team meetings, participate in calls, and even make one-on-one calls if permitted by the tenant’s settings.
  • File sharing and collaboration: Guests can access, upload, and collaborate on files shared within the Teams channels they have access to. This includes working with files in SharePoint and OneDrive for Business associated with the team.
  • Planner and tasks: If the team uses Microsoft Planner, guests can view and edit tasks assigned to them, helping them stay aligned with project timelines and responsibilities.
  • Use of chat feature: Guests can use the chat function to communicate privately with other team members, enhancing direct communication and quick exchanges of information.

To ensure transparency and security, Microsoft Teams clearly identifies guest users with a special tag. A “(Guest)” tag is appended to a guest’s name in the user list, chats, and anywhere their name appears within the team. This tagging helps differentiate them from regular members and ensures that everyone is aware of their external status.

While guests can participate in many ways, there are certain restrictions on their access to ensure organizational data security and compliance. These limitations might include restricted access to certain organizational resources, inability to create meetings, or limitations on administrative capabilities within Teams. We will cover these restrictions in more detail in the next section, providing a comprehensive look at what guests can and cannot do within Microsoft Teams.

👉 To learn more about the Microsoft Teams guest experience, please review the following Microsoft article: Guest experience in Teams.

Microsoft Teams Guest Access Limitations & Restrictions

To maintain security and control over corporate data, these interactions come with specific restrictions. These restrictions are crucial as they help protect sensitive information and ensure that guest users comply with the organization’s security policies.

So, what are the limitations of guest access in Teams? Below are several guest access restrictions designed to balance functionality with security:

  • Limited directory access: Guests cannot browse the organization’s directory. This means they cannot see the full list of users or groups outside of those they interact with directly within Teams.
  • Limited meeting controls: Guests may have restricted abilities in meetings, such as being unable to initiate a ‘Meet Now’ session or limited sharing capabilities.
  • No access to certain applications: Depending on the organization’s settings, guests might not have access to some applications integrated within Teams.
  • Restricted file access: Guests can typically view and collaborate on files shared within a specific channel but might not have the same access rights as internal members, such as downloading or sharing files externally.
  • Communication restrictions: Guests might be able to participate in chats and conversations but could be restricted from accessing certain messaging features like editing or deleting sent messages.

👉 What is Microsoft Teams guest access expiration? Microsoft Teams itself does not automatically expire guest access. However, admins can manually control guest access durations and revoke access as needed through Azure Active Directory, which supports setting expiration policies for guest accounts.

Managing and reviewing guest access in Microsoft Teams

To effectively manage and monitor guest access, Microsoft Teams administrators can use tools and settings provided within the platform:

  1. Setting permissions: Administrators can configure guest permissions in the Microsoft Teams admin center, where they can enable or disable specific capabilities such as calling, meetings, and messaging features for guests.
  2. Using Microsoft Entra B2B collaboration: This feature enhances the management of guest access by allowing administrators to set conditional access policies and multifactor authentication for guests. This ensures that guests can only access resources they are explicitly authorized to use and under secure conditions.
  3. Access reviews: Regularly reviewing guest accesses is crucial. Microsoft Entra ID Governance offers access review capabilities, allowing administrators to periodically review and certify the appropriateness of a guest’s access to resources. This helps in maintaining up-to-date access permissions and ensures compliance with security policies.

👉 For more detailed guidance on configuring and managing guest access in Microsoft Teams, refer to the following Microsoft documentation:

Microsoft Teams External Guest Access: Guest Access vs External Access in Microsoft Teams

When collaborating with individuals outside your organization using Microsoft Teams, you have two primary options: guest access and external (federated) access. Each serves distinct purposes and offers different levels of interaction and collaboration:

  • External access (aka federated access) allows Teams users to find, call, chat, and set up meetings with people outside their organization who are also using Microsoft Teams or other compatible services like Skype for Business. This type of access is ideal for users who need to communicate across different organizations without needing deeper integration into your Teams environment. Essentially, it extends the reach of your Teams to other users just as if they were part of the same network.
  • Guest access, on the other hand, involves adding individuals to your Teams as guests, typically via their email. Once added, guests can participate almost like full team members. They can join calls, meetings, collaborate on files, and more, depending on the permissions granted. Guest access is more integrated than external access, providing a richer collaboration experience.

👉What’s the difference: Microsoft Teams guest access vs. SharePoint external sharing? Microsoft Teams guest access provides external users access to Teams resources, enabling them to participate in channels, meetings, and collaborations. SharePoint external sharing is more document-centric, allowing external users to access, share, and collaborate on files stored in SharePoint or OneDrive.

When to use each type of access: guest access vs external access

Use external access when:

  • You need to enable quick, ad-hoc chats or calls with external parties.
  • The interaction does not require access to your organization’s internal resources like files or detailed collaboration on projects.
  • You’re looking to maintain a level of separation and security, keeping external users outside of your internal Teams environment.

Use guest access when:

  • You require ongoing collaboration with external individuals, such as contractors, clients, or partners who need to work closely with your team.
  • The external users need access to certain internal resources, such as files, documents, and other collaborative tools within a specific team.
  • Your collaboration scenario benefits from deeper integration, such as allowing guests to see and participate in the organization’s schedule or to utilize full chat functionalities.

👉 So, what is the difference between external access and guest access in Teams? External access allows Teams users from an entire external domain to find, call, chat, and set up meetings with you. It’s like having users from other companies available in your Teams directory. This does not allow for collaborative access to documents or team channels. Guest access, on the other hand, is more granular and collaborative, allowing specific external users to join teams and channels, participate in chats, collaborate on documents, and more, just as internal team members do. 

Below is a summary table of the differences between Microsoft Teams guest access vs external access:

FeatureGuest accessExternal access (federation)
DefinitionAllows specific external users to join teams and channels.Allows users from external domains to communicate via chat and calls without joining teams or channels.
Access levelCan participate fully within a specific team or channel.Limited to calling and chatting with users across teams.
CollaborationFull collaboration including chats, meetings, file sharing, and document collaboration within teams.Primarily limited to communication such as chats and calls. No collaboration on documents or team resources.
Control and managementManaged at a granular level by team owners and admins. Specific permissions can be set for each guest.Managed at the domain level by IT admins. No granular permissions for individual users.
Use caseIdeal for ongoing projects with external partners, freelancers, or clients who need access to certain resources.Suitable for regular communication with external organizations where detailed collaboration is not required.
Security and complianceSubject to specific policies and permissions set by admins. Guests can be given restricted access based on needs.Subject to domain-wide policies set by admins, focusing more on communication security.
Setup requirementIndividual invitation and configuration per guest.Domain trust setup and configuration between organizations.
