Overview: SharePoint Online Shared Calendars

A SharePoint shared calendar, also known as a SharePoint group calendar, is a user-friendly tool for managing team schedules, meetings, and other occasions. They enable teams to collaborate on projects, track milestones, and stay up to date. Shared calendars can be easily customized and integrated with other Microsoft 365 tools, ensuring that everyone in your team is on the same page. By using a shared calendar, crews can overcome scheduling conflicts and improve overall efficiency.  

The main features of SharePoint Online shared calendars are: 

  • Centralized event management: Your team members can view and manage events in a single location, thus saving time on switching between apps and searching for information. 
  • Customizable views: You can choose from different calendar views, such as monthly, weekly, or daily, depending on your needs and preferences. 
  • Integration with Microsoft Teams: With this handy integration, you can schedule and join meetings directly from the SharePoint online calendar. 
  • Event reminders and notifications: Set up reminders and receive notifications of upcoming events, so you don’t miss important meetings. 
  • Color-coding and categorization: SharePoint Calendar color-coding makes it easier to differentiate between various types of events and projects. 
  • Permission management: Administrators can control who has access to specific calendars, making sure that sensitive information is protected. 
  • Recurring events: With third-party apps like Calendar Overlay Pro, you can create recurring events for meetings that occur regularly, saving you time. 
  • Calendar overlays:  SharePoint calendar overlay is one of the most in-demand features that allows showing multiple calendars in a single view. 

 Shared calendars are indispensable tools for teams aiming to enhance collaboration. If you seek to centralize scheduling for your team, create a SharePoint calendar and enjoy easy tracking of events and milestones.
