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 sync.blue® 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 sync.blue® 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 sync.blue® dashboard.
