Exchange Distribution List Issue

I am trying to add someone to an Exchange Distribution list that already has 2 members that belong to it.

The problem is: The emails that are sent to the distribution list email address are not forwarded to the new user that I added to the member list on the distribution list. The original two members still receive the emails just not the new user that I added.

I see their name in the members tab on the distribution list properties window and I have restarted all exchange services to see if that would help. Still no luck.

I added another user within the domain to see if it was just a problem with the user I was currently trying to add and that user could not receive the emails either.

Not sure what I am doing wrong. We have multiple distribution list and I have added and removed many users before. Not sure why it is not working now?

Have you tried updating the GAL?

Do the following:
1. Go to the EMC > Organization Configuration > Mailbox Node > Offline Address book tab and click update on the Default OAB,
2. Restart “Microsoft Exchange File Distribution” service
3. Force Outlook updating OAB.
Restart Outlook or press “Send/Receive” and click “send/Receive Groups” and click “Download Address Book”

Also ensure that you have Exchange 2007 SP3 installed.

You could also try the shell command:

Update-GlobalAddressList - Identity "address list" -DomainController "domain controller name"

Open in new window

Have you done the tracking of the emails also check the logs and are you getting any error from that users (who are unable to receive email, NDR).

HendrikWiese: I tried your steps with no luck. The emails are being forwarded to the current members of the distribution group just not the new ones that I just added today. I can send an email from the distribution group to the users directly. But when I send an email to the group it will not forward to the new users.

Ahmed786: I have not done a tracking on the emails and there does not seem to be any errors on the application log for the last 4 hours that I have been trying to get this to work.

Ok, I logged into owa with the user I added to the distribution group and had her send an email to the distribution group and she received the forwarded copy from the distribution group as did the others. But, if I use any other email account to send to the distribution group, she does not received the copy of the email like the other two original members of the group do.

Does that help any?

UPDATE:

The Distribution group works if the email is sent from another user on the domain and is forwarded to all members of the distribution group.

I have already disable "Require that all senders are authenticated" from the get go so that is not the problem.

Still, I can send an email to the distribution group from a gmail account and the email gets forwarded to the original users of the distribution group but the the user I added today.

I am lost here, this should be simple, I have never had a problem adding someone to a distribution list on 2003 or 2007...

Any Ideas on where to look now?

1> You are telling that now you can send emails to DL from another account within the domain, so from certain accounts you are unable to send email, m i right ?

2> IF you enable "Require that all senders are authenticated" then external users won't be able to send emails to that DL.
