Since last week, a lot of our users are bothered by Outlook ‘s credentials prompt. Entering credentials just makes the prompt show again, only canceling it and clicking the “needs password” text in the bottom of Outlook’s main window allows them to keep working for a while.

So far 15 out of our 42 active Windows Outlook users have been impacted not counting Mac Outlook, or holiday users. Everyone is using Outlook on Windows 10, Office hybrid setup with all user boxes in the cloud. Yesterday I’ve had everyone delete their stored Windows 10 credentials. This looked like it solved it for a few hours, but today impacted users report the same behaviour. All are on the same hardware, so it’s very odd that not everyone is impacted.

There was no relevant change on our part afaik. Any leads to the cause are welcome. I’ve logged a MS case, with not much feedback so far. Starting in build The regkey disables WAM use in Office, which can degrade the auth experience users will see legacy UI and may be prompted more in other cases, so it’s only recommended if the situation is blocking. We highly recommend deleting the regkey once the fix is out.

In a similar case some time ago, I put Outlook in online mode not cached and prompt disappeared. Put it back to cached mode and all was good. You may want to look at any updates that are out there too. Sometimes you need some, sometimes, you got some and they screwed everything up. When I was running migrations, I was getting what you are alot. Microsoft – its what keeps you employed. We had that issue as well.

It seems dirsync on our fimsync server had outdated credentials so it wasn’t syncing with O We finally got Microsoft to admit there is a problem and are now waiting on a resolution. Even though they say our tenant is no affected by it, but it obviously is. This is also not showing up on the health report. Your patience is much appreciated and thank you for contacting Microsoft Partner Cloud Support.

Have a nice day ahead. Rohit Hajare Technical Lead: Email: v-2rohaj microsoft. Chanchal Kadu Team Manager v-2chak microsoft. Our dirsync was fine, and the MS support team asked me to send them Outlook logs which I did , then asked me to do some packet sniffing.

Looking at Nicabus ‘ post, I assume some other team has found a solution and implemented it. Thanks for sharing this background! Checking with our users the issue seems fixed. We are now pursuing a report from MS about what happened.

I’ll upload it here if I get one. Final status: We’ve completed the validation process and have confirmed that the issue is resolved. Scope of impact: Your organization was affected by this event, and this issue may have potentially affected any of your users attempting to access their Outlook Desktop client via a specific API. Next steps: – We’re reviewing code data to determine why it caused the credential prompts and to prevent similar problems in the future.

This is the final update for the event. Adding to what Nicabus mentioned, we also got the same response back from Microsoft. I found out that this problem appears in versions and above, so I’ve disabled automatic office updates and rolled back to version build Hoping Microsoft can fix this soon so we can go back to automatic updates for Office.

You’re still experiencing this issue? For us, and I guess for Nicabus too, the issue was solved in August After a password change it may take a while before our Hybrid setup catches on completely, but that’s usually solved in extreme cases inside 3hrs.

Issue has been happening since last Thursday September Issue progressively got worse. At first accepting my credentials, then not at all. Pop-up keeps appearing.

Outlook will not connect to the Exchange server. Now, this morning. Broken again. The pup-up asking for password keeps appearing and won’t accept password. I have ran into this with a customer running Exchange It will work for like a day. Then it will prompt the user for credentials with the full email and password. It’s almost like Outlook is changing the credentials and won’t accept anything other than the email address and password as login.

Please give some more info about your set-up. On-premises Exchange? O exchange? Are you the only one with that set-up? Have you tried reverting to another build?

Outlook is still synched with Exchange even though of the username password request. Exchange server is hosted by 3rd party company in another state. My HQ is in another state also. Other folks had issue several months ago. No solution, just a temporary work-around.

Had to create an additional pathway to Outlook e-mail box. At first, that did not work, but now seems to be working holding my breathe. Asking here as well. We’ve got exchange on prem and the problem happens only on machines running outlook Now that we’ve read here that it started in version , we’ve checking some user machines for version number and it shows as Same issue Devin, did you make any progress?

I rolled a few back revs but issue was still popping up. Users in my Org are now getting this, but it’s only affecting mobile users with Surface Pro 4’s. OST, removed everything from Credential Manager, and no joy. Microsoft has us going through the gamut of sending logs and finding nothing. We’ll fix it for a day or two, but then it’s back. Some users get the pop-up a few times a day, others get it a few times per hour.

Make no sense The issue most certainly is NOT resolved. Happened to me countless times in the past hour. Has been on on-going issue for me ever since I installed Outlook on my Windows 10 laptop over a year ago now. As I have several different email accounts, I have Outlook configured to poll all accounts for new mail every minute.

Sometimes I think this issue has gone away as I may not be prompted for password sometimes for several weeks. But sooner or later it always starts back with a vengeance and is going berserk today! Renders Outlook basically useless when this is happening unless you don’t mind dealing with the multiple account password prompts every one minute! I’m a private user, not on an exchange server. When the prompt shows up hit more choices. After you select more choices select other user option.

Another screen will appear and prompt you for the username and password and below that it should have populated the domain already.

This worked for me flawlessly after trying everything that was suggested on these sites. Let me know if this works for you guys too. Is your suggestion for Outlook ? In my case, when the password prompt appears, there is no “more choices” option. All I get is an Outlook prompt containing fields for the server, user name and password.

The fields are already populated with the correct information. You can also check the option to save the password. But the password is already correct. I’ve never changed it, but none-the-less, due to the persistence of the password prompts, have re-typed and re-saved the password hundreds of times to no avail.

 
 

 

Outlook keeps asking for username and password – Status: Fixed

 
BTW, I have also installed Mozilla Thunderbird to see if the same issue happens using their Oauth connectivity and there is no issues at all. Finally we opted to use the Sean Varley solution. To resolve Outlook password prompt issues, this is the perfect solution. However I have also run across the problem with Windows 7 Pro. One of my colleagues just solved this for an Office mailbox by turning off modern authentication on the local workstation.
