Add the Group Calendar via Outlook on the Web

Open Outlook on the Web

Navigate to outlook.office.com in your web browser and sign in to your Microsoft 365 account.

Navigate to the Calendar

Click on the Calendar icon located in the left-hand navigation pane.

Add from Directory

Click on 'Add calendar' in the side menu, then select 'Add from directory'.

Select and Add the Group

Search for your Microsoft 365 group by name, select it from the dropdown results, and confirm to add its calendar to your view.

Frequently Asked Questions

Why did my Microsoft 365 group calendar disappear suddenly?

Group calendars can disappear due to temporary server syncing issues, accidental removal from your left-hand calendar pane, or an administrator making changes to the group's permissions.

Will fixing the calendar on Outlook on the web restore it on my desktop app?

Yes. Actions taken in Outlook on the web sync directly to the Exchange server. Once you re-add the calendar on the web, simply restart your Outlook desktop application to force it to sync.

What should I do if no one in my team can see the group calendar?

If the issue affects all members of the group, it usually indicates a server-side problem or a misconfiguration in the Microsoft 365 Admin Center. You will need an IT administrator to check the group's health or escalate the issue to Microsoft Support.

Can I add a Microsoft 365 group calendar if I am not a member?

You can only add and view a Microsoft 365 group calendar if the group is set to 'Public' or if you have been explicitly added as a member or guest by the group owner.
