Outlook is auto filling a MicrosoftAccount\ prefix to my Username/email on the initial password prompt. I can't sign in without manually removing it.
I'm connecting to an Exchange server using Outlook 2016 on a Windows 10 machine with a Microsoft Account, not local account. Whenever I start Outlook, my email address is reported as "MicrosoftAccount\myemail@mydomain.com" (where myemail@mydomain.com is the email address for the Exchange server).
I have to erase the MicrosoftAccount\ from my email address, click OK and then I get logged on.
Is there a way to stop it from automatically adding that to my email/username?
