If you have an Exchange, Microsoft 365, or Outlook.com account, you can send a sharing invitation to other users so they can view your calendar in their own Calendar list.

Calendar sharing isn't limited to the default Calendar folder that is created in all Outlook profiles. You can create additional calendar folders and choose which of those folders to share. For example, you can create a calendar folder for a specific project and share it with your co-workers. Optionally, you can grant them permission to modify the events and appointments in the calendar.

  1. Click Calendar.

  2. Click Home > Calendar Permissions.

  3. On the Permissions tab, click the user's name and then choose Remove.

Share a calendar by publishing it to a web page

If you have access to a web server that supports the World Wide Web Distributed Authoring and Versioning (WebDAV) protocol, you can publish your calendar there.

Note: Not sure if your server supports WebDAV? Your server administrator or internet service provider (ISP) should be able to tell you.

  1. Click Calendar.

  2. Click Home > Publish Online > Publish to WebDAV Server.

    Notes: 

    • If your email account uses Exchange, you will see Publish This Calendar, instead of the option to publish to a WebDAV server. This lets you publish your calendar directly to an Exchange Server. In the window that opens, select the publishing options you want, and click Start Publishing.

    • If you're using Microsoft 365, you can still publish your calendar to a WebDAV server, but you must first remove {Anonymous:CalendarSharingFreeBusySimple} from the sharing policy. This will prevent you from publishing your calendar to Exchange in the future, however. 

  3. In the Location box, enter the location of the WebDAV server, select any other publishing options you want, and then click OK.
