Exchange 2013 - Default email address policy

Hello,

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:

http://technet.microsoft.com/en-us/library/4acc7f2a-93ce-468c-9ace-d5f7eecbd8d4(v=exchg.150)#CreateConnector

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 alias@contoso.com. 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@mycompany.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.

Thank you.

J

Default is fine.  For exchange you can change how you want them to login if you want to.

Exchange Admin Center > Servers > Virtual Directories >  OWA > Edit > Authentication

Here is where you can choose.

Basically all the above is saying is it is easier.  So lets say your name is john doe with a username of jdoe.  So with aliases configured on the exchange policy you email is: jdoe@consto.com.  jdoe matches your username and thats what the UPN is refering too.  

Now if you changed your email address policy so now the email address is john.doe@consto.com, this does not match your username and you will have to enter in your username.

Its not difficult but basically trying to get you to avoid a step and making things easier.

If the alias and the email address do not match then this is why some people have to enter domain\user in order to logon to OWA. This is good to know and it finally makes sense. I wondered why some people could use the email address but some people had to use the domain\user. I will accept the defaults. Thanks.
