Remove securiy update (KB5000871) from Exchange server 2016 CU19

We recently upgraded our Exchange 2016 servers to CU19 with security patch KB5000871.
After the Upgrade the transport service will not start on one server.
Can we safely uninstall KB5000871 without affecting the exchange server / CU ?

We have run out of options and we want to see if uninstalling the patch remedies the problem.
Please help
Thanks

Hi, @hdsouza

Sorry for the late reply.

You may uninstall the securiy update and reinstall it. It won't have an effect on your Exchange server.

Please follow the best practices in this document: Description of the security update for Microsoft Exchange Server 2019, 2016, and 2013: March 2, 2021 (KB5000871)
