    I have a macbook pro running Outlook 2011 which has been working fine for three weeks.

    Yesterday however, whilst using free BT Openzone to connect to internet, I get a 17900 message which claims it is to do with the username of password.

    However I can login via webmail every time.

    I should point out that I have numerous accounts and it happens to one of them randomly - rarely the same one constantly.

    I have tried using my iPhone's Hotspot connection to and its the same problem.

    Baffles and seeking assistance.

    Does the same account with the same settings work in Apple's Mail app?

    I googled the title of the thread, Outlook 17900 error, and it listed a number of Microsoft support pages that tell how to solve the problem. If none of those have been tried yet, I recommend starting there, with Microsoft's support pages.
