Using Outlook for Android in business environments for email and scheduling
I also have this issue.
All was working well until my exchange server required a password change. Following that I can no longer access my exchange server via the Outlook mobile app.
I can access the account from Outlook desktop and the web interface.
I use two devices, a Samsung Phone and a Samsung tablet. Both will now no longer let me into the exchange account.
The exchange account is a custom domain name.
I have tried clearing the data and cache, uninstalled and re-installed all to no avail.
Please help.
