We have MFA enabled for all users. It is working perfectly normal when accessing Office via the web - they get prompted for MFA. With the Outlook desktop client, however, users are prompted for the modern authentication prompt but are not prompted for MFA.

We don't have Azure premium so it's not an issue with the trusted IPs. I had a case open with Office support, but they are claiming this is the normal behavior even though their documentation says otherwise. Has anyone encountered this issue before where Outlook does not prompt for MFA when using modern authentication?

If you dont have Modern auth enabled, MFA is useless. Enable it, there is no downside really. Just make sure your clients are updated to a relatively new version.

Just encountered this in testing on my own account last week. The Office desktop apps are not compatible with MFA. Microsoft says you must go into your o account to create an app password.

My head was about to rotate trying to figure it out as there is no valuable feedback from the desktop apps other than repeatedly asking for a password. Once I created an app password, I fed it to Outlook in place of my actual account password. It accepted this unique password and carried on. Haven't tried with iOS Mail. Shawn is correct. You need to use an app password for Outlook. Microsoft's instructions for generating the app password are here. Sorry to disagree, but their documentation here shows how to enable it for and it is enabled by default for Are we talking about two different things?

I'm referring to Multi-Factor Authentication, where you are required to respond to a code sent via text message or respond to the Microsoft Authenticator app on another device. We're talking about the same thing. Modern Authentication is what allows you to log in with MFA enabled. The Outlook login is similar to the web login.

Multifactor authentication for Office 365: A step-by-step guide

Originally, this was not possible with Officebut they added it at some point within the last 2 or 3 years. It is working in our lab with our test Office tenant. And in production, it works but ignores MFA users use their normal password not an app password. Evan's link is the same one I found yesterday when trying to "fix" my own testing. It specifically states that Office needs an app password, and the document was updated Mar 26 this year. We're either at a transition point or one hand isn't talking to the other.

One thing I've found with Microsoft and particularly with Office is that they often have contradicting or outdated documentation in different places. The result of my support ticket with Office was them telling me that MFA being skipped is "by design" even though I explained to them that their own documentation states otherwise and showed them that my other tenant is working 'normally'.

I was hoping someone on here had some ideas. Agree with you Shawn. I wasted a ton of time trying to login to my Outlook after starting to test MFA. It's stalling me rolling out MFA any farther as it's confusing when to use which password for me I understand now - how will users understand which to use when.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

Contact your administrator usually the person who gave you the Office account to see if there is a different verification method you can use, such as your office phone or a smart card, until you replace your mobile phone.

Though documentation is sketchy, is appears that all newly created tenants in have OAuth 2. However, it cannot hurt to check. This will take a few minutes to fully propagate through your tenant. However, once this is done, you will be able to turn on MFA for your users, and they will be using the standard OAuth 2. OAuth 2. Thus, once it propagates out, once a user closes and reopens Outlook, it should prompt them for the MFA credentials.

For iOS on the other hand, it is not as clean. As of iOS 12, the easiest method to force it to use OAuth 2. Hi, I just want to say that this post saved my life during a deployment and hours and hours of troubleshooting and headache. An outstanding share! And he actually bought me dinner because I stumbled upon it for him… lol. So let me reword this…. Thanks for the meal!! But yeah, thanx for spending time to talk about this issue here on your web site.

I just went through this process and it also seemed to me we would need to use the App, which is not the case. Thanks for the information! This set me on the proper path for resolution but did not work for me as described. My problem is that with MFA enabled I was not able to connect using powershell.

I needed to log into Office, go to Exchange Admin, Hybrid navigation on leftconfigure multi-factor authentication. This needs to be done with IE, edge did not work. It runs some code and opens powershell. Your article was a great help. Typically having Chrome or Firefox as your default helps.

Lemme guess…you would get an odd blank rectangle pop up when using Powershell, it would disappear, and then get an error? Granted, we manage our devices with inTune so it automatically reroutes the setup to login to intune. Any suggestions? Unfortunately my experience with InTune is extremely limited, but it sounds as if the InTune is set to act as a proxy for the logins.

So we've had some trouble with the MFA lately. Which wasn't a good start for us if you ask me. When this was fixed I waited a while to enable it again.

I started gradually this time and it worked fine. But after a while some users noticed that when they are trying to configure their email account on a new computer or phone they just get an error saying something went wrong. I have my mail configured on my work computer with the app password I created when I got asked to login again after MFA had been enabled and that worked just fine.

I had to login to my phone as well and that's where the problem started. I created a new app password for my phone but no matter what I do I can't get my phone to accept either my actual password or the app password. I've tried with multiple app passwords without success. If I disable MFA for my account it will work perfectly however.

So there is something wrong with MFA and I don't know how to troubleshoot it. From your description, I can see that your problem is you cannot login into neither Outlook client nor Outlook app on mobile after enabled MFA. Given this situation, may I know whether you are using Outlook client? For your reference: Enable modern authentication in Exchange Online. If not, you can try deleting the existing app passwords and re-create it, then clear Outlook credentials by following steps below see if it can help:.
