Is there a way to make the email address policy use only lower case letters even if the Name information in ADfollows the usual practice of capitalizing the first letter of the first and last names?TBrennan

I'm not sure I'd agree this would be a "usual practice" but you should know SMTP is not case sensitive and therefore the setting does not matter. Here is another thread in this context:http://social.technet.microsoft.com/Forums/en-US/identitylifecyclemanager/thread/331a9814-f62d-4dcd-a366-d2d0eb3d296e

SMTP may be case insensitive but we use the email address as the basis for user certs and that is case sensitive so we have been manually changing the SMTP address to all lower case after creating each new mailbox. I was hoping there was a way to have the email address policy do that automatically.TBrennan

Interesting. I'll research this and post back any options I find.

Powershell can convert strings to lowercase as described here. You could possibly put all the addresses into the pipeline, lowercase them and then put them back. I'm not sure if it will report "no change" during this operation, as this happens sometimes with case-insensitive fields. If this is the case we could set it to something incorrect, then set it back correctly with the correct case.Sadly my lab is inaccessable right now so I cannot test this or put a script together for you. Is this something you'd be interested in? If so, I can post back later in the week.

After seeing your first reply I was thinking along the same lines; I'd have to first remove the requirement to apply the default email addresspolicy (we have to do this when we modify the SMTP address manually) and then recreate the entry. I will try it in our test domain and see if I can get it to work.Thanks.TBrennan

cool, please post your results!
