When a user wants to give another person access to one of his or her own mailbox folders in Outlook, the user has to grant the other person access to the specific folder that the user wants to share and also to all other parent folders in the folder hierarchy. It's not enough for the user to grant permissions only to the specific folder that he or she wants to share.
For example, user B wants to grant user A access to the Invoices folder, and the Invoices folder is a subfolder of the user's Inbox folder. To grant this access, user B has to grant permissions to user A for the following folders in Outlook:
- The Invoices subfolder
- The Inbox folder
- The parent Mailbox folder
