Using Recipient Policy to Create Email Addresses

By default, Microsoft exchange uses the username when creating email addresses for users using Recipient Policy.

eg.

username@domainname.com

However, in many cases the standardised email address format is slightly different – for example:

firstname.lastname@domainname.com

This is actually really easy to edit in the Exchange System Manager using a few variables:

%g  = Given Name (First name).
%3g = means first 3 letters of Given Name
%s  = Surname (Last name).
%3s = means first 3 letters of sn.
%d  = displayname.
%m  = Exchange alias.

Once this has been edited, just right click on the Policy and click Update this Policy now.
