Weird distribution group issue

[mcseguy9]

I have a user who receives e-mail sent to an Exchange 2007 e-mail distribution list, but she's not a member of that list. I have verified via the Exchange Management Shell that she is a member of one distribution list, which happens to be a mail enabled security group. The commands I used to verify this are:

Get-DistributionGroup | where { (Get-DistributionGroupMember $_ | foreach {$_.name}) -contains "yourUserName" }

Get-DistributionGroup | where { (Get-DistributionGroupMember $_ | foreach {$_.PrimarySmtpAddress}) -contains "yourUserPrimaryEmailAddress" }

Any ideas as to why this could be happening?

Possibilities:

1. Someone who is a member of the list has set those e-mails to be automatically forwarded.

2. The list she is a member of is somehow linked to the other list.

3. The list that is used for the e-mails that the user is not a member of and should not be getting e-mails from is corrupted. It may need to be deleted and rebuilt.

Thanks for the ideas, jdc2000.
