Hi @ViumanFernandoChacn-8350 ,
All users have this issue or only specific users have this issue?
1.Please check the DNS record and make sure the the configuration is correct, especially the Autodiscover record is correct.

2.Please using the Microsoft Remote Connectivity Analyzer to test the Outlook connection, Autodiscover service will also be checked. If there is an error, please share the specific error information, but please cover your personal information. Please refer to: Microsoft Remote Connectivity Analyzer.

3.If only the specifiic have this issue, please try to clear the cached credentials in the computer's credential management or try another computer to see if the configuration can be successful.
