PS F:\>
To solve the issue you need to perform now the following steps on the affected Exchange Server:
1a.) Open the registry and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\UnifiedMessagingRole
1b.) Create a backup from the Watermark registry key
1c.) Delete the watermark registry key
2a.) Open a file explorer and browse to C:\Program Files\Microsoft\Exchange Server\V15\UnifiedMessaging
2b.) Inside that folder the subfolder “grammars” and “prompts” should be missing. If that is the case you need to create them.
Optional: As the folder are empty you might restore the content now from a backup or if you do not have a backup you might try to copy the files from a Exchange server with the same patchlevel which do not have this issue. However in most cased the content isn´t needed as the upgrade should copy them from the ISO.
2c.) Re-Run the upgrade in a CMD (via run as admin):
Setup.exe /mode:Upgrade /IAcceptExchangeServerLicenseTerms
Note:
Some blog posting mentioned to copy the setup folder from the Exchange 2016 ISO to C:\Program Files\Microsoft\Exchange Server\V15\bin\. However this temp. will work as well. However during the next CU installation, this will cause the issues reported here due to the wrong files. So if you run into the error 1619 you should try the solution above at first.
