I'll give this a try before the longer solution posted above. At least on my side it seems to possibly be related to a recent 1802 build of Office ProPlus, our Semi-annual builds are not having the issue. Once I waited for the Quick Steps bar to load at the top of the screen and tried again it worked. Still very unusual, because after reboot it "looped" through the authentication prompts several times without fixing.
#Outlook for mac disable mfn full
A full shutdown and restart caused message to appear on both computers.
Can't verify yet if issue is isolated to 2FA users though.ĮDIT 2: Well, I was able to resolve on both. Happened with two users now, both using 2FA.
#Outlook for mac disable mfn password
It is only after it is working then that person's password expires and gets changed in Active Directory that the issue occurs.
Gregory for Microsoft?ĮDIT: So when we set it up initially, any new user will see the dialog properly appear for the password. I'm beginning to think this is a Microsoft issue and not just a corrupt user profile. Seems to be after we enabled modern authentication for our tenant and once passwords expire. Well, now we're having this issue as well. I'm still trying to put all of the pieces together to determine a solution for this one. I don't mean to hijack this thread - what I've mentioned above is a workaround. After entering the user credentials and opting to have them remembered, the clients have remained connected. After opening Outlook back up, I was greeted with the basic authentication password prompt. Setting this key to 0 disables Modern Authentication within the Outlook client. HKCU\SOFTWARE\Microsoft\Office\16.0\Common\Identity\EnableADAL I've done so by implementing the following registry key (DWORD (32-bit) Value) after closing Outlook: The workaround that I've implemented is to turn Modern Authentication off for the clients that are experiencing the issue. After researching Modern Authentication, I read that it uses a token that expires after 90 days, which could have something to do with the issue. Their passwords were set to expire after 90 days, but the intermittent connectivity leads me to believe that this was not a password issue. A reboot would fix the connectivity, but only temporarily.Īnother thing that I noted was that it had been about 90 days since these users had been migrated to Exchange. Clicking on 'Needs Password' would quickly flash a white box, just like OP mentioned. When it did disconnect, the user would see the 'Needs Password' message in the bottom right-hand corner of Outlook, as well as a 'Type Exchange Password to Connect' message (under a key icon), in the Send/Receive tab of Outlook. The first thing that I noted was that the users were seeing this issue intermittently, and Outlook/Exchange seemed to disconnect after a certain period of time. I recently ran into this issue on several PCs in our environment (Windows 7/10, Office 2016 Home & Business), and it seemed like more PCs were experiencing it as time went on. Hopefully we don't run into more of these or someone finds a resolution that doesn't require setting up a fresh profile for the user. I think that just translates to there is some kind of setting, file or registry entry causing this and we don't know what. It just wouldn't make sense that this was caused but a "corrupted profile". Either with his mailbox or something with a recent patch. I've got to think that something occurred on Microsoft's side. I mentioned this to MS who said that I must also have something corrupted in my user profile. This also would not automatically configure properly. Microsoft used this as proof that something was "corrupt" in his profile.įor testing I also tried creating a new Outlook profile on my computer with his account. After creating the new user profile Outlook was able to automatically configure his account. Went through a bunch of stuff with Microsoft support and finally ended up creating a new user profile. I tried creating him a new Outlook profile but it would not automatically configure his O365 account. I tried repairs of his Office as well as a full uninstall/reinstall with no change. The window that popped up was not the same size or position that the password dialogue would be. Clicking on that brought up a window that immediately disappeared without seeing anything on it. Saw the same Needs Password where it would normally say Connected to Exchange. I had the exact same issue on a client system that also started on the same day.
