Are there any known issues with adding an on prem exchange account to the Outlook mobile app? Keep getting error unable to log in. Check username and password. Password is not the issue. I've tried domain\username and username both for the username but neither work.
If it's a shared box, don't believe you can. Otherwise, presuming autodiscover records are published? Are you choosing 'Exchange' option when setting up in the app?

I noticed they stated in another post (5-days ago) that the “New” Outlook for desktop doesn’t support connections to on-prem exchange servers, but that it will be added later. I’m guessing that this is one of the “unexpected features” of the latest mobile app update.
Still having issues however some mobile devices will add the accounts when others will not. It seems possible an issue with the android app but not 100% certain.
I am facing the similar Issue that below:
Dear Expertise,
In my on-premises Exchange environment, some users are unable to log into Outlook mobile devices. However, these same users can log in using other mobile email apps such as Gmail or the default email app.
Here's the scenario:
A user's email address/SMTP is "active.jhon@abc.com" and their logon address/UPN is "actusr@xyz.org". The user is unable to log in to mobile Outlook using the email address/SMTP "active.jhon@abc.com", but they can successfully log in using only their logon address/UPN "actusr@xyz.org" if they select it as the email address.
I have also tested using Microsoft Connectivity Analyzer, and it passed. However, users are still unable to log in to mobile Outlook using the "active.jhon@abc.com" address, while other mail apps can log in successfully. I have checked all URLs, and they are configured perfectly.
How can I solve it.

Previously, when adding a new user to the Outlook Mobile App on Android or iPhone, you could directly select the "Exchange" option. However, this choice has not been available since the update in early April.
To configure a new account in the Outlook Mobile App, you must enter the User Principal Name (UPN) instead of the usual email address.
For instance:
Use <alias>@domain.local instead of <alias>@ExchangeEmail.com
After entering the UPN as the email address, you can add an Exchange account.
I hope this clarifies the process.
