Out-of-date- connecting on-premises exchange servers
Hi
I am getting issues with sending emails. Please find snapshots. I have done Pause Enforcement for 10 days. It is working fine now but I need permanent solutions.
- What version of Exchange Server are you using onprem?
- Exchange Server 2016 CU19 (15.1.2176.14)
- You need to install the most current Exchange Server CU to be updated.
See more here: https://techcommunity.microsoft.com/t5/exchange-team-blog/update-on-transport-enforcement-system-in-exchange-online/ba-p/3827774
You can find the CU here: https://support.microsoft.com/en-us/topic/cumulative-update-23-for-exchange-server-2016-kb5011155-98183ada-e4cd-465f-b201-69d40fb74678
Warning: patching an old Exchange Server may result in a very bad day, so prepare and make sure to do it when you have the time for troubleshooting, if something goes wrong.
Kind regards Thomas.
