Why does Microsoft Outlook keep asking for Password

I just did what you suggested and it did NOT work, in fact, now can't even access outlook!!!

"Remove your credentials from the Credentials Manager: Open the Control Panel and navigate to User Accounts > Credential Manager. Under Windows Credentials, locate any entries for Outlook and click Remove. Restart Outlook and enter your login credentials again"

This does NOT work. In fact, it will deny you access to your outlook pst file!!! Clearly, you are suggesting things you've never done yourself. Shame on YOU!

Hi Michele,

The problem has been used by Microsoft migrating their email servers from the old IMAP servers to more secure authentication.

Microsoft sent emails out about a month ago about the change, without acknowledging the issues being reported.

There is guidance on which versions of email applications will work in the future. I run several outlook and hotmail accounts on MacBook, iPhone and Windows machines.

On my MacBook I had to delete each of my outlook and hotmail accounts in the "Internet Accounts" setup, where I had configured them years ago using the imap server addresses. I re-added them selecting "Microsoft Exchange" and entering the email account and password. Actually easier than the old imap addressing. I let them synchronise and all is good on my MacBook.

I had to do the same for one of my accounts on my iPhone.

On one of my Windows machines, the older one, I also had to delete and re-add one email account within the email application settings. In windows there was an additional option in setting up a new email account, "Outlook.com", which I selected.

My newer windows laptop was all good and didn't need any changes, probably because when I bought it I set it up in the new way anyway.

I will add that I have previously setup two step authentication for each of my accounts. I don't know if that is required for the new setup or not.

I hope this helps.

Thanks for your reply. The issue I had about the "password" was resolved months ago. However, I haven't yet moved onto the new Outlook programme and am dreading having to start learning lots of new things. Why do they keep changing things!!

Viewing this post through my iPad there doesn’t appear to be much of an issue with Microsoft outlook, but reverting to my PC repeated issue with password request is still driving me bonkers. With respect to upgrading to the new version of Outlook this is not an option for me. I run an act! CRM. system that integrates into Outlook through add-ins which only operate on the old version of outlook. The system just doesn’t record the information that I require to do.

Microsoft! This is a real issue for so many people out here, please get on and get the problem solved .

Microsoft, just please effing MAKE THIS STOP!!!

It has been a constantly problem on BOTH my computers. Nothing in this thread has ever worked to solve it. I've nuked and reset the Outlook profile multiple times on both machines. I have ran with O365 mail accounts from 3 different domains in Outlook for YEARS and never had a problem until about the last year. Sometimes I can go a week without being prompted for credentials. Other times like today it will do it half a dozen times a day on EVERY account.

I have specifically had to BLOCK MFA from deploying on 2 business domains because of this constant issue. This bug is effectively resulting a massive security hole because it would be completely unusable with MFA active and the constant login prompts (I tried it for a week before I had to go in and disable it in a rage).

I'm seriously considering abandoning O365 and MS over this and the future of "new Outlook".
