Due to a recent change in Microsoft 365, the access to Exchange mailbox folders via the active check check_mailboxes could fail with an error message like this:

Unhandled exception: ErrorAccessDenied('Not allowed to access Non IPM folder.')

With this werk we update the version of the package exchangelib to v5.2.1, fixing the respective error handling.
