How can I configure SBS 2011, that users can login with their E-Mail address?
Right now, users have to use either <NTdomainname>\<userloginname> or <userloginname>\<addomainname>.  But it is not possible to login with the e-Mail Adress.

Examples for Usernames to login with OWA:
ntdomain\perolin  works fine
perolin@ntdomain.local works fine
perolin@domain.com is not recognized for login (default e-mail address)

Environment: SBS 2011 (Windows Server 2008  DC, Exchange 2010 …more or less out of the box installation)

The primary email address should be the same value as the userPrincipalName.If you specify the PrincipalName attribute, the User name field on the Outlook Web Access logon page requires a UPN address. This logon method works only for users whose UPN name is the same as their e-mail address.

To be picky, it is not possible to login as the email address, because the email address has nothing to do with the domain credentials.

What you can do is configure a new UPN with AD Domains and trusts that matches the email address, then change the user account properties of each user so the UPN matches their email address. Therefore as far as the end user is concerned it is their email address they are using.

However that will require manual changes to the user accounts after creating them in SBS. Furthermore, I have never made the change on SBS so I don't know if it will upset anything. It is a common change on full product.
