Hi, I'm wondering if anyone having issue today after the Microsoft Authenticator update (Version 6.2405.3618) on Android? My Outlook app suddenly asks me to sign in again with our Office 365 work email, and if I tap on sign-in, it will show "Updates required - One or more of your apps are out of date. Please update your apps to continue" error message (I also have sign-in issues with Word, Excel, Microsoft 365 Admin apps, but for some reason OneDrive and Intune are not affected). After multiple re-tries, I ended up clearing Outlook app caches and data. After that, I'm unable to sign in to my Office 365 work emails as either it is stuck on the spanning circle or the same "Update required" error message, but my personal free Outlook email with MFA can sign in without issue. I've manually checked the Outlook app and Authenticator app on Play Store and both show no updates. I also clear Authenticator app data and recover everything from the backup, but still the same issue. (I'm on RedMagic 8s Pro with Android 14)
Outlook (Version: 4.2421.1)
Microsoft 365 Admin (Version: 5.4.0.0)
Microsoft Word (Version: 16.0.17628.20074)

Same issue on IPhone.
Hi Christy,
I did posted this issue there first (https://answers.microsoft.com/en-us/outlook_com/forum/all/outlook-app-suddenly-ask-to-sign-in-but-shows/9605236c-cd9a-49de-82a5-68a4bd8c6f4d ) but I was direct to here because the moderator believe it's Authenticator issue.

Hi @Tinmor Chen ,
Thanks for your reply!
I notice that you have added Microsoft Authenticator tag, please wait for professional suggestions.
Hi Christy,
After many tests, it definitely is the Authenticator issue, I completely uninstall it from my phone, and everything start to work, I can sign in all my work emails back onto Outlook app using SMS verification and no longer have "Update required" error on all Microsoft apps, but once I install Authenticator back, even without open it after install, same error start to appear. so I believe the update of Authenticator from yesterday must have bug. I installed older version (6.2404.2872) and everything still working fine, then I updated it back to version (6.2405.3618), and the "Update Required" error starts again.

I confirm that uninstalling MS authenticator mitigates the very same issue with Teams. It is a shame that Microsoft has not taken any actions after that much time to solve the problem at once.
Hi Arantes,
After long troubleshooting, I finally figured out the issue. If you also has enterprise office 365 account, after the new Authenticator update, it requires "Microsoft Intune" installed (if you are using "Company Portal" it no longer works with Authenticator version 6.2405.3618 or above) and all stand-alone office apps like Word, Excel, PowerPoint no longer works too, need to replace using "Microsoft 365 (Office)" which is replacement for the stand-alone apps for enterprise office 365 account.
