HOW TO: Prevent annoying spam from your own domain

It’s easy to get a list of all members of a Distribution Group. The Exchange shell (EMS) ships with the Get-DistributionGroupMember cmdlet that makes it a short one-liner (compared to 100s of lines of code in VBS). However, how do we get all Distribution Groups a user, group, or contact is a member of? There’s […]
