An interesting problem was pointed out to me today. A reader reported the directory "TransportRoles\data\Temp\UnifiedContent" within the Exchange installation directory, which contains a lot of data and keeps filling up the hard disk. I then had a look at my private installation and was also able to find some very old data in the directory in question. Here is a screenshot ... Read more

Although the virtual directories for the various Exchange web services can be recreated via the "Exchange Admin Center", there are cases where this function reaches its limits. I have simulated such an error for this article. Even after resetting the directory for OWA with the Exchange Admin Center, OWA does not work: Not everything ... Read more
Exchange 2016 databases can also be restored from a backup to other Exchange 2016 servers. The database therefore does not necessarily have to be restored to the server on which it was backed up or was active. It does not matter whether the server was a member of a DAG.
