Exchange 2019 certificate renewal-in hybrid environment

Question

Dears,

our SSL certificate will be expired in two weeks, so we renewed it and assigned exchange services as shown below, I have read on some articles that if both certificates old and new are matched then we don’t have to make any other changes on send and receive connector on premise side, please explain more about that part

Regards .

Hi @Ibrahim AlHusari ,

I have checked Transport services logs on my send and receive connectors , they were using the new certificate Thumbprint is that enough ?

That would be enough.

Actually, based on my understanding, you can just proceed to remove the old certificate, if the connectors are still using the old one, you'll be prompted with the error below and will not be able to remove the old certificate:
