Exchange 2013 Change OWA Log on Options
In Exchange 2013, by default the log on options for OWA are DomainnameUsername, in Exchange 2010 we could change this in the ECP, this functionality is currently not in the Exchange 2013 ECP, so we must use power shell. In the example below we change it so OWA authentication is user name and password only and also so that a user can log into Exchange with their email address.These commands also apply to Exchange 2010.
Before
owa 2013 log-on options
Powershell to Change OWA Authentication to User Name
Set-OwaVirtualDirectory "owa (Default Web Site)" -LogonFormat Username -DefaultDomain techieshelp.local
iisreset
With the command above we set Exchange 2013 OWA to be user name only.Then restart IIS for the changes to be effective.
After
Exchange 2013 OWA Username only
Powershell to Change OWA Authentication to Email Address
Set-OwaVirtualDirectory "owa (Default Web Site)" -LogonFormat PrincipalName
iisreset
In the example above we set Exchange 2013 OWA to log in as Email Address (Principal Name ).Then restart IIS to enable the changes.
After
log into owa with email address

Great tips.
Allen, I have been trying to set basic authentication so I can publish OWA and match the authentication, currently set as Forms-Based Authentication in the exchange. When I look at the website (owa default) it says basic, but TMG 2010 complains as follows:
Testing https://webmail.domain.com:443/OWA/
Category: General error
Error details: The authentication delegation method defined in the rule does not match the authentication method selected for the published directory on the server hosting the site. Publishing rule authentication delegation method: Basic. Published server authentication methods: Forms-Based Authentication.
Action: You can change the authentication method on the published server or select “No delegation, but client may authenticate directly” in the Authentication Delegation tab of the publishing rule.
Are you able to help? Much appreciated
Joe

Hi Joe, I’m not a TMG man unfortunately, I can spell TMG but that’s as far as it goes
. Digging around brought up this article on Technet

They looked to have had the same issue as you?
