Hi guys!

Is it possible to use AutoDiscover without entering login in pop up window? I will try to explain.

My outlook auto configuration is working, but on the stage Search for username@mydomain.com server setting, Im getting login/password challenge from Exchange server.

A window appears where login field is set to UPN (e.g. usermame@mydomain.com).

I found similar on the Internet:

Then I change it to mydomain\username, enter the password and auto configuration succeed.

User logins (UPN) in my AD are no the same as usermame@mydomain.com.

Is it possible to force AutoDiscover work without additional inputs?

For example set up default realm on virtual directory like with OWA or something?

Exchange servers 2010 & 2013. Outlooks mostly 2010.

You can set UPN to be same as SMTP address.

Otherwise, you'll get this prompt unless your Windows logon is the domain account.
