Configuration new Outlook for Mac

The new Outlook for Mac is not recommended with the KIT mailbox (Exchange On-Premises account). There are several functions that do not work or work poorly. Use the legacy Outlook for Mac instead.
- Synchronization unreliable
- Name suggestions very unreliable
- Contact folders are displayed flat
- Shared calendars cannot be opened
- Additional mailboxes cannot be added with the "wrong" configuration
- Functional mailboxes cannot be added using your own user account. The user's own account is added instead.
- etc.
