Describe the bug
For Shared mailboxes, the listed permissions are insufficient:
Mail.Readbasic
Mail.Read
Mail.ReadWrite
One of the following is required:
Mail.ReadBasic.Shared
Mail.Read.Shared
Mail.ReadWrite.Shared
To Reproduce
Steps to reproduce the behavior:
- Make a call to a shared mailbox without above noted *.shared permissions: (GET https://graph.microsoft.com/v1.0/users/{user-ID}/mailFolders)
- (Notice the 403!)
Expected behavior
Would expect the "modify permissions" tab to have the appropriate *.shared permissions for shared folders visible and available
Screenshots

Additional context
Easily fixed by adding the .shared level permissions
