Environment is Exchange 2013, clients are OL 2010. Have one user stating that she is still receiving emails from two different distribution groups that she is no longer apart of. Both Distribution groups are "Global" and I've verified that she isn't part of them as well as in Exchange admin center.

Where or what can I do?

Thanks,

Is there other DG that is nested in the 2 DG that she no longer part of?

Is there a powershell command to run to find out what distribution groups a users is a part of. I'm not seeing a nested DG.

Look at her AD account in Active Directory Users and Computers and check the 'Member of' tab.

Try the following

get-aduser -identity "username" -properties memberof | select -expandproperty memberof

Hi,

This script will tell you what distribution groups a user is a member of.

$User = read-host -Prompt "Enter Username"
$user_dn = (get-mailbox $user).distinguishedname
"User " + $User + " is a member of the following groups:"
foreach ($group in get-distributiongroup -resultsize unlimited){
 if ((get-distributiongroupmember $group.identity | select -expand distinguishedname) -contains $user_dn){$group.name}
 }

And please use this command to check the members of that two distribution groups that user isn't a member of.

Get-DistributionGroupMember Identity Group name

Then compare these two results, if there are same distribution groups in the two results, you will know why this user receive emails from two different distribution groups that she is no longer part of.

Best Regards.
