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.
