Using PowerShell to Manage Distribution Groups in Exchange 2007

This is a quick post for a small task I found the basis for the commands in Ying Li’s post here.

We had an admin leave us and go to Facebook recently.  She was a member of a TON of our distribution groups set up for all of our Amazon Web Services account.  Well, I couldn’t go into ECM and remove the user from the groups, and there were a bunch of them, so I really didn’t want to click each individual group and remove her.  So, I did a quick google search and strung a command together remove the user from the groups.

All of our AWS accounts start with AWS, i.e.  So, this is what I came up with:

Get-DistributionGroup "AWS*" | Remove-DistributionGroupMember -member oldadmin

That worked like a charm.  So, I then ran this command to add myself to those same groups:

Get-DistributionGroup "AWS*" | Add-DistributionGroupMember -member mrichardson

That too worked like a charm.  I had some other cleaning up to do, so I encorporated a couple other commands to remove the old admin from all groups.  That required two different commands:

Get-DistributionGroup "*" | Remove-DistributionGroupMember -member oldadmin
Get-SecurityGroup "*" | Remove-SecurityGroupMember -member oldadmin

Of course I got errors for the groups she was not a member of, but that was to be expected. That pretty much sums it up.  Hope this is helpful for someone.
