Exchange mass mailing one existing accounts email to old account
Posted on 2010-09-23
We have Exchange Server 2007 running in the office. The system has been here prior to me so I am not sure of configuration details and I just know the basics of Exchange.
There is a group email address that sends to everyone on the @abc.com domain.
An old blackberry email address which was supposedly canceled or the account changed within Exchange returns a Delivery Status Notification error to whoever sends out a group email. firstname.lastname@example.org ... I go to the distribution group and that user has a email@example.com account and there are no other duplicates.
Today the problem escalated...
Another user firstname.lastname@example.org also used to have a email@example.com account which has been deleted or changed to the new one. There is no trace of it in the system that I can see. No one has received any Delivery Status Notification errors from the marge@blackberry account though the firstname.lastname@example.org account is on the same distribution list as email@example.com.
Until today, everyone in the company that had sent email to firstname.lastname@example.org received Delivery Status Notification Failures from email@example.com in bulk. Some received none, some received 100s -- with the same subject lines of whatever that user had send to firstname.lastname@example.org.
Subject: Re: Analytics www.abc.com 20100823-20100829 (ABC.com
Sent Date: 31:42 +0000
has not been delivered to the recipient's BlackBerry Handheld.
So for example... I received 31 Delivery Status messages like above for each email I had sent email@example.com from my abc.com exchange account within the last almost month.
I am at a loss. Any ideas? Let me know if you need clarification.
