Hello All

My customer has Exchange 2016 CU5 and along the way someone has updated the server to .Net Framework 4.7.0. What can I do about updating .Net Framework and getting Exchange to CU14 supported by .net 4.7.2 or CU 16 supported by 4.8?

Is it fine to follow Josh’s advice and put the server in maintenance mode and then update to 4.7.2 or 4.8 and then install the respective CU14 / CU16.

4.7.0 is not supported by any CU so I don’t have a safe upgrade path.

Thank you

Thanks for these many articles about Exchange Server. I have been turning to them often.

I have an Exchange 2016 mailbox server running RTM. The current CU is CU11. Would you suggest risking the Exchange 2016 RTM to CU11 upgrade or simply upgrading to Exchange 2019? If the former, do you know of a document describing steps of a similar successful upgrade? If the later, I would want to use the Desktop Experience on Server 2019. Thanks.

[…] Exchange 2016 CU10 and Exchange 2013 CU21 require .NET Framework 4.7.1 be installed on the server before you install the CU. This requirement was called out as far back as September 2017. If you have a scenario where you can’t see a path to upgrade .NET and Exchange while staying within supported combinations of the two, refer to this article for guidance. […]

We are currently running Exchange 2010 with the latest rollups to date (as of Sept 18th of this year) on a box with Server 2008. I’m trying to install a new Exchange 2016 VM on a Server 2016 host, but my prerequisites have halted me because my AD forest level must be 2008 R2 or higher. I need to get my hands on an older CU, before they jumped the Forest prerequisite up to 2008 R2. Any advice for me?

Hello, I have a DAG with 3 nodes with Exchange Server 2016 CU1 and .NET Framework 4.6.1. We want to update directly to CU10.
What would be the procedure if I do not have the other CU?
