Exchange: Hide All Contacts From Global Address List
KB ID 0001564 Problem I saw this on EE this evening, so I thought I’d work it out, what if your Global Address List is full of external ‘contacts’, and you want to remove/hide them? Solution First take a look at them, to see you’re not about to cause any damage!

Exchange: ‘Can’t find the Organizational Unit that you specified’

Exchange 2016 Migration to Exchange 2019
KB ID 0001472 Exchange 2019 Migration If Exchange 2016 was Exchange 2013 in a pretty dress, then with Exchange 2019 it’s simply added a hat. In the past, every third Exchange release was a major rebuild, but Exchange 2016 is simply Exchange version 15.1 (Exchange 2013 was 15.0 and Exchange 2016 is version 15.1).

Exchange 2007 / 2010 Update Rollups Wont Apply
KB ID 0001454 Problem I had to do an SBS 2011, (Exchange 2010) to Exchange 2016 migration last week. The Exchange 2010 installation had not been updated for a long time, anyway common sense dictates that you should always upgrade the old Exchange server to the newest version first. But every time I did, the install launched, started, stopped, then rolled back the changes, and failed. Setup wizard for Update Rollup {version} for...
