Hey guys, anyone know how to limit the number of recipients per message by OU or perhaps some other AD account atrribute?We have an Exchange 2007 environment.Can we do it by Powershell?I'm talking about an Education environment here, need to place a big restriction on Student accounts, but leave staff at default settings.I can see how to do it individually (no thanks) and I can see how to do it for everyone.But thats not what we need.Mr Google does not seem to have the answer!Thanks for any tips.Regards Peter.

Use server side filtering for OU and client side filtering for various Exchange related AD attributes...For anOU:Get-Mailbox-OrganizationalUnit "DomainName.com/BranchOU/Users" -ResultSize Unlimited |Set-Mailbox -RecipientLimits 100For an AD Attribute:Get-Mailbox -ResultSize Unlimited| Where{$_.CustomAttribute4 -eq "Students"} |Set-Mailbox -RecipientLimits 100Reference:Working with Command Outputhttp://technet.microsoft.com/en-us/library/bb123533.aspxHope this helps...!!! Am I better than Mr. Google... ? ;)Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
