Previous builds which are out of support stop being available at some point through official channels. This is why you need to keep the installation set of any build you have running in production, should you ever need it again. Try to to get an earlier build through your TAM or support channel.

Check the Upd HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\Patches\DisplayName for the latest version reference, replacing GUID with 442189DC8B9EA5040962A6BED9EC1F1F for Ex2019 and 442189DC8B9EA5040962A6BED9EC1F1F for Ex2016. Or use a script like this one: https://github.com/michelderooij/Get-ExchangeVersion

Thank you so much for this list. With the world of Exchange burning and starting with nearly 0 information as to how Exchange versioning works copy/pasting this data into a spreadsheet so I can sort the data made it super easy to figure this out! As a matter of fact this data helped me identify the fact that MS released KBs to patch older, unsupported CUs of Exchange and provide that data to our research team.

hi all

Iam trying to upgrade my exchange 2016 from CU17 to CU18 or 19, and always end with the following :-

Error:

The following error was generated when “$error.Clear();

initialize-ExchangeUniversalGroups -DomainController $RoleDomainController -ActiveDirectorySplitPermissions $RoleActiveDirectorySplitPermissions

” was run: “Microsoft.Exchange.Management.Tasks.InvalidWKObjectException: The well-known object entry B:32:B3DDC6BE2A3BE84B97EB2DCE9477E389:CN=Help Desk\0ADEL:e8371ddb-7994-424a-ae57-b91f9d8c7f58,CN=Deleted Objects,DC=taqniaspace,DC=com,DC=sa on the otherWellKnownObjects attribute in the container object CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=taqniaspace,DC=com,DC=sa points to an invalid DN or a deleted object. Remove the entry, and then rerun the task.

Message implies the Exchange security groups (necessary for RBAC) have been deleted recently or in the past. To remediate, you can try running Install-CannedRBACRoles.ps1 and Install-CannedRbacRoleAssignments.ps1 (located in $ExchangeInstallPath\Scripts) after you looked at their actions (restore default RBAC roles and assignments).
