I am setting up an Exchange 2013 server, and I am configuring the default email address policy while following the instructions in the following URL:
I am looking at the Default Policy of my Exchange 2013 server. If I edit the default, and it is listed as SMTP, all my choices are greyed out, but I can enter a custom address type if I want. I can also add Email Address parameters.
It looks like the default email address format is firstname.lastname@example.org. I think I like this because I want the alias to always match the smtp email address prefix.
While reading the technical URL I listed above, I noticed it says the following:
"We recommend that you configure a user principal name (UPN) that matches the primary email address of each user. If you don't provide a UPN that matches the email address of a user, the user will be required to manually provide their domain\user name or UPN in addition to their email address. If their UPN matches their email address, Outlook Web App, ActiveSync, and Outlook will automatically match their email address to their UPN. "
What does this mean and how does it apply to what I want to do? I don't want people to have to enter domain\alias but instead I want them to be able to enter email@example.com when logging into Outlook Web Access.
Please let me know if I should add a new default policy, or if the default is good enough. Also, what does the quote above mean and how do I prevent that behavior from happening in my environment.
