In reply to Mike. Security updates are incorporated into cumulative updates, so you can install the latest CU followed by the latest SU and you should be good to go.

Hi Tony,

Are the security updates cumulative, or do I have to install each monthly security update sequentially?

I found conflicting answers online, so…

Thanks
Mike

CU20 is now out of date. You should be on Exchange 2016 CU22. https://support.microsoft.com/en-au/topic/cumulative-update-22-for-exchange-server-2016-kb5005333-ceb154d8-7116-43a5-83c1-205af7c43764

I’m a little confused. After upgrading to CU20, do I also need to install the two ISU sec updates? I thought they would be included but the more I look at the more I think I didn’t really patch the server very well!

Thak you for the info provided, Tony. As a double check, I am looking, on the MS site, for info regarding the need for the schema update for Exchange 2013. In the KB page you linked in the article, under installation instructions, it is not mentioned at all. Where can I find this information please? Best Regards!
