    Good morning,
    I've been having this pop up for about a week and a half on my Surface Pro 4. If I clear it, it just pops back up five seconds later. If I type in my Microsoft Account password, it just vanishes then reappears almost instantly. I figure it has something to do with Office 365 but I'm not having any sync issues or anything like that. Honestly, I don't know what it is. Could someone more experienced then me let me know?
    Thanks,
    Zachary

    You may want to go on Microsoft and change your password. The Cnet.com and us Malwarebytes and run a scan... Maybe be nothing, but you can't be too safe.

    Before anything I would follow ClintRo's advice and do whatever scans possible to be confident this is a legitimate com surrogate window. Com surrogate is another name for dllhost which is sometimes spoofed in Trojan/virus attacks.

    Having said that: Do you use two-factor verification for your Microsoft Account? If so, you need to enter an app password in the password field. When you don't enter the right password it doesn't prompt you. It just disappears and comes back again as you described.

    Info on app passwords and Microsoft two-step authentication:

    I do use two-factor authentication, of course. I'll run my scans to make sure then I'll go fetch an app password. Thanks for the help guys.
