I have a ticket already with Microsoft, but I haven't heard from them for a few weeks and I'm not too happy with their support anyway. This issue (a more serious issue actually) dates back to June for me, I have dozens and dozens of screenshots and it's NOT just with Outlook, though Outlook sticks out since I usually only have that opened up. I think there is some bug going on with the combination of this GPO, the broker plugin, whitelisted IP addresses,Īnd the machine leaving the domain during sleep mode (wireless stays on and changes IP, maybe that triggers the bug?) Now, I'm not sure if this is causing the issue or not, but we didn't have problems until we enabled 'Site to Zone Assignment List' GPO.
Had an issue where he couldn't even use his Outlook at all (or Publisher.which we just opened as a test), everytime we killed Outlook and reopened it, the blank MFA window would just pop back up.
This isn't that big of an issue for me personally, but for my confused/angry users, they want a fix. You have to kill the task via task manager. The issue with this blank MFA window is that you cannot use Outlook, nor close it or do anything. I believe this is Microsoft AAD Broker plugin failing. Whenever myself or a few other users come into work and dock our machines (in this case Surface Pro 4s), everytime our machine wakes up and Outlook is open, we get a blank MFA box that fails to load.
