On the main machine where I have been using the suite, now my account is deactivated and if I try to authenticate, it looks like it works but then get the "Fix", "Authenticate", "Activate" or "Resolve" buttons, all of which do nothing. I had this exact issue on another machine, that after 2.5 hours on the phone with MS support (via Zoom), the solution was to Outlook Login Issues Troubleshooting uninstall MS Office 365 and reinstall it. Yeap, you describe it exactly and unfortunately we still don’t have an answer. Closed the window without entering anything and Outlook returned to ‘Connected to Exchange’.

Microsoft 365 Login Loop because of MFA

When I try to sign again it will be stuck in sign in loop with the message " Taking you to your organization sign in page" after I have logged in on my company site... When I log in to my account at first from a new device or after a while, it stays signed in and I can work peacefully for about an hour, then it automatically signs me out. Or, any suggestion on how to fix this issue, even better. I do NOT have this issue with the other laptop, an iPad, a MacBook Pro and tablet.

• To make a long story short we’ve since been asked to collect Outlook logs and install Fiddler to capture additional logging.
• Create your account and connect with a world of communities.
• When we opened the old, existing profile it didn’t ask for ANY authentication, it just started working.
• @Microsoft, given the level of attention the community has given this issue, I hope you come up with an update soon.
• Today was the first time in about 2 months that I had the issue.
• We are looking at using conditional access policies where a user with a Domain joined PC is not prompted for MFA.

Fix constant sign-in prompt for Microsoft

In each case the fix has either been one of the Fix Outlook Not Opening After Windows Update above items or a combination of them. There doesn’t appear to be any pattern to the issue occurring or the problem being limited to any specific computer or user. So figuring that was the same issue here, I did the same thing.

Outlook stuck in an MFA loop

The bad thing is this account was not registered with Microsoft Authenticator, so I couldn't see any codes in the authenticator. And there were no other login options, and I was stuck in a login loop. This is now the 2nd machine that presents the same issue. I have a valid MS 365 subscription that includes 5 device licenses.

We are looking at using conditional access policies where a user with a Domain joined PC is not prompted for MFA. Right now we have it set to prompt when a user is not on any of our corporate networks or they are using a mobile device. The user had Office 2015 and Office 2016 credentials and Teams credentials that we deleted. We checked with Word that the account was connected–it Office 365 sync problems and login fixes was and the we opened Outlook and it immediately connected. We too have been seeing this more and more, all W10 on O365, although we use Okta as our MFA.
