One of the common requests that you are likely to receive as an Exchange administrator is to generate a detailed report of which recipients are members of one or more distribution groups. In this recipe, we'll take a look at how to retrieve this information from the Exchange Management Shell.
To view a list of each distribution group member interactively, use the following code:
foreach($i in Get-DistributionGroup -ResultSize Unlimited) {
Get-DistributionGroupMember $i -ResultSize Unlimited |
Select-Object @{n="Member";e={$_.Name}},
RecipientType,
@{n="Group";e={$i.Name}}
}This will generate a list of Exchange recipients and their associated distribution group membership.
