Hello
I've just updated an exchange server to CU 20 ,SU 3 to Cu 21.
All went as plan but now
Server build is Version 15.1 (Build 2308.8)
Exchange forest Schema Version = 15334
Exchange domain Schema Version 13241
Nothing in logs showing issues and all service look to be OK
BUT
when I try to install
Security Update For Exchange Server 2016 CU21 (KB5007409) via windows update
I get this
Installation status: Failed
Error details: Code 8024002D
I download the file but when I run it from CMD , as administrator.
it can't find the MSI . I direct it to Install drive for CU 21 but I get this
Reinstall CU didn't help
Any help would be appreciated

I would like to confirm with you: what did you mean by "Reinstall CU didn't help"?
Did you restore the server from backup and reinstalled CU21? -

https://www.microsoft.com/en-us/download/details.aspx?id=103645Be sure to reboot the server before trying the manual install.

2021-11-16T13:21:44.22+00:00 Can you run the health checker? See what build it reports and any installed Security Updates?

2021-11-16T15:17:17.383+00:00 I've pointed it to my install directory
E:\Program Files\Microsoft\Exchange Server\V15
and
E:\Program Files\Microsoft\Exchange Server\V15\Setup
Can't find MSI , I searched for *.msi and didn't return Exchangeserver.msi file
Yes , I do have another , Updating it now using the same process as before . Will report back once It finished

2021-11-16T14:36:23.757+00:00 Yea, its right there:
Exchange IU or Security Hotfix Detected.
Security Update for Exchange Server 2016 Cumulative Update 20 (KB5003435)
Security Update for Exchange Server 2016 Cumulative Update 20 (KB5004779)when prompted for the msi does it work if you browse to the setup files where Exch is installed? Versus where the Cu21 setup program is?
Also, is the only server you have seen this on? Looks like you have more than one

2021-11-16T19:06:32.613+00:00 Never seen that and the only fix I can find is:
http://jurgenvm.blogspot.com/2016/10/installing-update-rollup-21-for.htmlNo idea if that will fix it though or if you want to even attempt that.
