I have around 10 different departments with different e-mail addresses and the previous admin bunched everyone into one policy before the migration to 2010 which I recently upgraded so now I can edit it. What is the best practice for setting e-mail address policies? Should each e-mail domain have it's own policy? When I make a new recipient and goto that users properties and select the e-mail addresses tab it only shows me smtp address from the default policy. I can manually remove all of those and add the correct e-mail address no problem, I'm just wondering is this the best way to do this?

I would not suggest you to have 10 different policy for 10 department. Email address policy could be define at domain level or site level. If your domain is sharing single address space then you should have one policy. Finally its depend upon your ORG need and decesion. If you want to change email address for department wise then you should create email adress policy and then push from there. Don't forget to add SMTP domain in accepted domain if you going to do this. Good Luck. Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

Hi, As my test, Email address policy could also be apply at OU level. You could create 10 OUs, such as: sales, services, technical and so on. Then create a private Email address policy for each OU. The new user in one OU will have only one correct Email address. You could drag the old users to the correct OU, the primary Email address will be changed due to the Email address policy. You don’t need to remove the old Email address manually.

So if I seperate by OU all I have to do is create the policy and apply it to the correct OU? Do I need to edit any custom attributes? Will this also recurse into any OU's I have under the main OU that I set these changes for ?

>>So if I separate by OU all I have to do is create the policy and apply it to the correct OU? Yes, it is correct. >>Do I need to edit any custom attributes? No, you don't need. >>Will this also recurse into any OU's I have under the main OU that I set these changes for ? Yes. It supports. But the Email address policy applied to the child OU should with the lower propriety than the parent OU.
