Exchange 2007 distribution group not sending to external contacts

Hi all,

Exchange 2007 on SBS '08. I run an internal group for domain users so we can blast messages through the co. And I knew I could create a contact with no domain permissions as well so I did that and put them in a group. It is for outside sales reps.

I noticed two errors, first when I add them to the TO field it refuses to expand the group.
It says: "Cannot perform the requested operation. The command selected is not valid for this recipient. There was an error while expanding the list. The list was not fully expanded." Does this every time I click the + sign. I shrugged at it but sent some test emails anyway. Not a single one left. I checked through-traffic through my third party spam filter and it apparently never left the server.

Did I miss some step or add them wrong?  

I put them in the users folder under my business. There is another generic Users folder but it is mostly filled with security groups so I didn't put them there.

If you created them in ADUC then they are not mail enabled, which is why they aren't working.
However you don't have to recreate them - just go in to EMC and choose New Contact, then when prompted, choose to use an existing contact. You can then select the ones that you have already created.

Where did you create the contact?
In ADUC or in Exchange? It sounds to me like the contacts are not mail enabled. Look in EMC, do the contacts appear there?

TimberJonDirector of ITAuthor Commented:
Yea created in ADUC. I'm guessing they should be showing up in the mail contact area of EMC, which they aren't. Can't move them. So I will remove from AD and re-create in EMC.
TimberJonDirector of ITAuthor Commented:
Drat. I didn't think of using existing contact since I thought EMC couldn't see them due to being in the AD. At any rate it only took me 2 minutes to re-create the dozen contacts I was playing with. Thanks Sembee and welcome back.
