An “0x80190194” Outlook error can occur in Outlook if users try to update their client with Exchange Offline Address Book (OAB). This error occurs if the Web delivery is allowed for your OAB file only. Let us know about the downloading process of the OAB file in the client Outlook.
Possible error causes
This implies clearly that the files requested by the client are not found while using a WSUS. It is typically a WSUS mistake, so that the files are incomplete.
I have also found cases in which the cause for the error is cited as inadequate access rights to a computer. It was a missing Eula file which caused the error in this older post.
