March 2021 Exchange Server Security Updates for older Cumulative Updates of Exchange Server
Dear The_Exchange_Team I would like to plea to quickly bring up a new page like CU Archive at docs.microsoft.com that include the links to the unsupported CUs.
We found many customers have not adopted the CUs and now end up with unsupported state and we need the stepup CUs for the .net upgrade dependencies.
Currently you remove links to all non supported CUs. It would be most helpful if the crucial CUs that are needed to get to 4.7 / 4.8 remain linked.
thankfully they are still available when using google.
example EX2016 CU14.
Some customers have installed the lastest CU over a very old one without watching the .net compatibility and face serious issues that needed to restore the Exchange. Thanks for your point of view if you intend to ease the situation.
There are still many unpachted system and the priority remains.
