Exchange 2010 - Limit number of recipients by user/group

Posted on 2011-10-10
Last Modified: 2012-05-12
I've got an exchange 2010 server, and we're having some issues with people sending out emails to too many recipients.  So, I wish to limit the max number of peopel my users can send to.  The only problem is that I need to leave this open for a select few (my HR department)

I'm aware how to limit this system wide, but don'y know if this is possible on a per-user basis.

Any Suggestions?

    It can only be done on the org lever, on a receive connector, on a hub server or on a specific mailbox

    what you could do is run a script, say nightly, that will set the max recipient for all users in your organization to whatever number you want (e.g. 10) and then for all members of the HR to e.g. 1000

    something like

    $mbxs = get-mailbox -resultsize unlimited

    $mbxs | % { set-mailbox $_ -RecipientLimits 10}

    $hr = Get-DistributionGroupMember HR

    $hr | % {  set-mailbox $_ -RecipientLimits 100}
