Hello,
I have got exchange on premise 2019 where I use to connect only ActiveSync.
When I configure my Outlook on the computer it's working, but when I tried to configure Outlook Mobile on my mobile phone with these settings:
e-mail: j.smith@Company portal .com
mail server: mail.contoso.com
Domain\user_name: domain\jsmith
Password:*******
I've got an error:
Login error
The connection to your mail server has expired. Check your mail settings.
How to resolve this problem? Is it the issue in exchange settings?

Hi @drClays ，
To narrow down the issue, could you tell us what version of Outlook you're using? Is it the Outlook for IOS or Outlook for Android? Whether it has been updated to the latest version?
In addition, please run the ExRca to test the Exchange ActiveSync with this account to see if it is connected healthily.
If possible, please provide the full screenshot about it for our better research. (In order to avoid the disclosure of your privacy, please remember to hide your personal information).
Hi @Aholic Liang-MSFT ,
thank you for your reply.
I run the ExRca and it's a problem with Autodiscover Post request.
This is screen from test:
Hi,
Sorry to reply late.
Have you tried connecting to Exchange from a computer that is not joined-domain? Is the same issue?
If yes, please have a check that the Autodiscover record is correct in DNS and that the external virtual directory is set up correctly.
Verify all the Exchange Services are running and the autodiscover app pool is started. Restart the sevices if necessary.
