We're working with a few groups to implement mailbox limits. To assist their users, I've been working on a report that breaks down the users into a few basic size limits. This function takes an array of IDs (Distinguished name field required) and returns a fairly basic HTML report back.
I am using the Quest AR Powershell cmdlet to read a group membership for my source data.
$SourceGrp = "Finance Department"
#Read in group membership.
