Exchange: Create a PFX Certificate and Import a Private Key

KB ID 0001528 Problem On my test network I have an Exchange server (Exchange 2016). As it’s publicly available and connected to Office 365 it needs a digital certificate.

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).

Forward Mail From Exchange (On-Prem) To Office 365

KB ID 0001467 Problem WARNING: Do not do this, if you are carrying out a Hybrid migration to Office 365! I’ve been doing an On-Prem to Office 365 migration recently. It was a little unusual because the ‘on-prem’ Exchange was not in the clients domain. So rather than migrate all the mail to their domain, and them migrate it to Office 365  we chose to use a third party migration solution ODME (Quest On Demand Migration...
