Mobile Outlook update (4.2411.0 iOS / 4.2410.0 Android)
Hello all,
Does anyone know if something changed with the most updated version of Outlook for Android and iOS? The app would not authenticate no matter what I had entered.
I had app config policies setup to auto populate domain and username fields, but after the update the app was not authenticating with the username (samaccount) and the domain I had set in the config policy.
Once I changed the username (after troubleshooting for awhile) to email address and left the domain blank the app would authenticate.
- We have also experienced this issue. What worked for us was the same change as you did.

Labels: Outlook for Android Outlook for iOS - So far, we found outlook mobile will take email address as UPN account to authenticate with AD.
and if fill the right UPN in email address field, it works.
I think is a bug related to the new version outlook mobile authentication logic~- Thanks for the update on this!
- Anyone else back to having this issue? Messing with the user name never worked for us, but it did start working for a few days but we are back to people unable to login. Looks like there are others in another thread having problems again too.
- yes I just ahad a user experience the issue today appears to be back again.
It's back again for us too. This time instead of an authentication error our users are being prompted for their Microsoft accounts. We're on-prem, no cloud--they don't have MS accounts.
- For whatever reason, the Outlook Mobile app on both iOS and Android is allowing us to login successfully just like in the past. That is what the domain name entered and the regular network user ID used and NOT the email address. Can anyone confirm on their end?
The issue seems to be resolved on my device as well. I did open a case with MS and know they said they were getting reports and looking into the issue. BrentH72
- We had the same issue, your workaround works like a charm. Thank you.
NickD_DG As of yesterday I have two cell phones that appear to have updated Google Play and then we had to install an Outlook update. Once this outlook update was installed, after the Google Play update, Outlook no longer authenticates to our corporate email server and authentication fails on the devices that loaded this update.
- We have also experienced this issue. What worked for us was the same change as you did.
"Once I changed the username (after troubleshooting for awhile) to email address and left the domain blank the app would authenticate. "- We did not create a ticket with MS.
we also seen to be experiencing this issue but using the email address as the username does not resolve our issue. what exchange version are your running?
- We are running Exchange 2016 CU 23 or 24 using basic authentication at the moment.
- We are having similar problems with our iOS devices and Androids. Just started this week. Tried the solution above but no luck.
