Increased collaboration is a perk of faculty and staff all being in the same O365 mail environment. You may want to consider what information is available to the public. Review your calendar permissions through the steps below.

2. Select the calendar you want to hide.
3. On the Home tab, in the Share group, click Calendar Permissions.
4. Click the Permissions tab and select Default.
5. In the Permissions section set the permission for Read to “None” to hide all calendar information, or to “Free/Busy time” to show availability but hide meeting details
6. Click OK to save your changes.

Outlook for Mac

1. From the top navigation, select File, then Folder, then Permissions.
2. Select the calendar you want to hide.
