Outlook: Error – Something went wrong
Recently on one system the client received an error when opening Outlook; “Error Something went wrong. [1001]”. Sometimes with Error Tag: 48v35, and others with Error Tag 58tm1.
Google suggests this is a very common problem with many suggestions as to how to resolve. In almost all cases, comments advise the suggestions did not correct the problem. I knew this PC had been offline for more than a month, so I suspected an authentication issue. In the end I found signing out of Outlook (File | Office Account | sign out), close Outlook, then reopen Outlook which prompted sign in again, resolved the problem. It also forced re-activating Office apps, and re-authenticating OneDrive, but all working fine when complete.
