To share calendars within your organization, you can enable external calendar sharing for all users in your organization. Once sharing is enabled, users can use Outlook Web App to share their calendars with anyone inside the organization. People inside the organization can view the shared calendar along with their own calendar. To enable calendar sharing, follow these steps:
- In the Microsoft 365 admin center, go to Settings -> Org Settings.
- On the Services tab, select Calendar.
- On the Calendar page, choose whether you want to let users share their calendars with people outside of your organization who have Microsoft 365 or Exchange. Choose whether you want to allow anonymous users (users without sign-in credentials) to access calendars via an email invitation.
- Choose what type of calendar information to make available to users. You can allow all information, or limit it to time only or time, subject, and location only.
Once sharing is enabled, calendar owners can extend invitations to specific users. To share your calendar, sign in to your Microsoft 365 account using a web browser and select Calendar -> Share. Type the name or email address of the person you want to share your calendar with in the Share with box. This box works just like the To box in an email message. You can add more than one person to share your calendar with.
