Hi Exchange team,

You give the SU the same file name regardless of the CU it relates to.

For example: -

August SU for 2019 CU11 is Exchange2019-KB5015322-x64-en.exe

August SU for 2019 CU12 is Exchange2019-KB5015322-x64-en.exe

So, I always check the file hash of the SU before I install it.

Here is the confusion; the Exchange2019 SU file hashes listed in the KB5015322 don't match the actual file hashes?

I’ve checked the file hash of the files downloaded from the Blog URLs, and the KB5015322 URLs, they don’t match the hash table in KB5015322 (see below)

Am I missing something? I'm using 'Get-FileHash .\Exchange2019-KB5015322-x64-en.exe'

 

Table from KB5015322 document...
