Exchange pop3 and outlook username format

Hello Experts,
I am trying enable pop3 service for exchange users. In this regard, I have enabled exchange pop3 service on exchange. I have set Plain Tex Logon ( Basic Authentication) method on exchange server. I have also enabled port 25 and 110 on my firewall.

I setup outlook client and it working using the username format as domain username. Its not working when I provide smtp email address as username on outlook 2010.

Any help and suggestions

Thanks

I am using exchange server 2010 SP2. But for now I want to use POP3. During the outlook configuration as pop3 I provided domain samaccount name as username in this case it's working but I when I try to use email address as username it doesn't work.
As I already wrote - unless the domain has been configured, the email address doesn't work for login information - you have to use the Domain information.

The usual format for POP3 is domain\username\alias.

Outlook Anywhere is far superior to POP3. I would actually go as far as to say that there are no good reasons to use POP3 and it has no place in a corporate email environment.

Simon.
Also want to add. Going forward Exchange 2013 uses Outlook Anywhere by default.
Hi Experts,
I have done the following and its working but have 1 issue.
- I created additional ( xyz.com) under Active Directory Domains and Trusts.
- I Changed the logon format on the exchange server in the Form Based Authentication section from default "Domain\User" to "UPN" and restart the IIS services.
- Selected the UPN Suffix in the properties of the user object that corresponds to this specific SMTP domain

I can login using UPN but I am not able login using primary SMTP address.

my UPN is test100@xyz.com
smtp address test1000@xyz.com

Please any help.

Thanks
