Using Outlook for Android in business environments for email and scheduling
I am in the same boat. The generic email app allows me to access my work account, but any attempt to run my work account through a Microsoft app (Onedrive, Office, Outlook) gets me the error occurred message. I can open my Hotmail account through the app, but not my work. I even did a whole phone reboot, and tried installing the app first thing....still no success.
Before I exchanged in my old phone (S7 Edge), that had my work email functioning through the Outlook app...I deleted the app and tried to reinstall it on my S7 Edge. Got the same error message I am receiving on my new S9+.
Also, I have 2 coworkers who purchased the S9 and S9+ a month prior to me, and have no problems accessing the outlook app and their email.
Frustrated.
