Exchange – Change OWA Login to Username Only

KB ID 0000861 


The procedure for changing the user login process from domainnameusername to just username, is a little different with Exchange 2013.

OWA username only


1. Connect to the Exchange admin center > Servers > Virtual Directories > Select OWA > Edit.

OWA Settings Exchange 2013

2. Authentication > Select ‘User name only’ > Browse and select the domain > Save.

OWA authentication user name only

3. At the warning click OK > Windows Key+R > cmd {enter} > Run the following command;

iisreset /noforce

Restart IIS

Note: This will (by default) also change the logon method for the Exchange Admin Center.

Exchange Admin Center Username
