Outlook and Windows Security Popup Box RRS feed

  • Question

  • All of a sudden, my Outlook cannot send messages. I get the dreaded Windows Security Popup box and nothing I do will make it go away.

    My Outlook worked at 8:00 AM.  At 11:00 AM, it quit sending messages.  I have had this problem off and on for three months.  I've spent days with Microsoft Support and spent an hour today with ATT.NET Support.  I can see my email on ATT.NET, using the same password.  I tried changing the passwords on both sites.  ATT.NET works, but, no dice with Outlook.  Still get the Pop Up.

    Today I uninstalled Outlook 2016 and purchased Microsoft Office 365.  I downloaded and reinstalled the product.  I completely set up Outlook from scratch.  I tried creating a new profile.  Nothing I do has helped.

    From other threads I have seen, this is a recurring problem.  Is there any solution? 

    I purchased Assure and spent several days with tech support trouble shooting this issue and now it is back again.

    I have always liked Outlook, but, am reaching the point of no return.
