Microsoft 365 (Outlook for Mac) - Unable to open/subscribe to a calendar due to a permission error
When you attempt to open/subscribe to a another calendar via Outlook for Mac, you receive the error below:
The reason for this error is:
- You have not been granted the necessary permissions - at a minimum, you need "full details" permissions to open a calendar. Any permission below this level will cause this error and the calendar will not be opened. Ask the owner of the calendar to confirm/verify the permissions you have been granted.
