New-EmailAddressPolicy "testmmmi" -RecipientFilter {((MemberOfGroup -eq "CN=studentDDG,OU=Student,DC=someschool,DC=com") -and (RecipientType -eq 'UserMailbox'))} -EnabledPrimarySMTPAddressTemplate 'SMTP:%m@student.someschool.com'I have tried this. Exchange seems accept the command. But the policy is not functioning. I can see the created policy, when I apply the policy, it shows its works fine. But the mail address does not creating according to the policy. I have deleted all other policy so that I can trace this is the only one on top priority. But no luck. Please help.

You should use real attributes in AD such as company, extensionattributeX etc. to base recipient policy on. Dont use backlink or calculated attributes to filter on.http://support.microsoft.com/kb/304516http://blogs.technet.com/evand/archive/2007/02/13/using-memberof-with-recipientfilter.aspxthe reason is that although you can use other attribute such as memberof, it will only work sometimes depending on if the userobject is updated or not.lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

Yes as Lasse said donot use the backlink attriutes. The best practise would be to use the AD attribute which is populated or shown in the Drop down box while creating the email address policy under the Condition section Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Thanks Lasse.
