Sync public folders from Microsoft 365 Exchange Online

After Microsoft deactivated "Basic Authentication" for Exchange Online in 2022, it is no longer possible to simply store access data in the® dashboard in order to synchronize the contacts of a so-called "public folder". Instead, a new "app registration" must be created once in the Azure Active Directory so that® receives reading rights for the contacts. Finally, a new connection with the source "Microsoft 365 - Exchange Online (Public contacts)" can be selected and set up as usual via the® dashboard.
