Free/Busy status migration
The Free/busy info is a feature of MS Exchange Server provided by Availability Service. This is not something that is migrated, it is kind of data that is derived from another data. Starting MS Exchange Server 2007 free/busy info is generated live based on users mailbox calendars. CodeTwo software migrates calendars items so if your target server is configured properly then this server will populate free/busy info based on migrated items.
