Sharing mailbox
Jeff Harlow Hey Jeff, when using folder permissions in Outlook the person who is sharing a mailbox must grant "Folder visible" permission on the root folder of the Exchange mailbox as well. If not configured you're not going to be able to view it properly in the navigation pane when it's being mapped. I found this explains it well https://support.microsoft.com/en-us/office/manage-another-person-s-mail-and-calendar-items-afb79d6b-2967-43b9-a944-a6b953190af5?ui=en-us&rs=en-us&ad=us
ChristianBergstromYes. That is checked.
Jeff Harlow Then you just have to add it as an additional mailbox to get it "stuck" in the navigation pane and work the folder permissions as well (per folder).
ChristianBergstrom I did that, but then they were only able to view the Inbox folder and no subfolders. Geez. This would be simplified if MS would just give us a reviewer permission from the admin portal!
Jeff Harlow That would make things easier yes. But you do have PowerShell as well

This cmdlet differs from the Add-MailboxFolderPermission cmdlet in that it modifies existing permission entries.
