this is very elusive. I can't reproduce this *under normal cirumstances*, i.e. create a user account with mailbox, create another user account without a mailbox, create a group, mail-enabled it, add both user accounts to the group, send a test message to the group.
The groups that do not work are built like this: - each customer has a separate OU - inside the customer OU there are all the user accounts and group accounts for the customer. - each customer has a global security group AllUsers@[customer.com] and every customer's user account is automatically added to the group. The group is mail-enabled. - Each customer has an account called Service (UserPrincipalName=Service@[customer.com]), Service is also a member of AllUsers@[customer.com] group. Service account does not have a mailbox. - Messages sent to AllUsers@[customer.com] get stuck in "Awaiting Directory Lookup" queue. - If I create a mailbox for Service, messages flow normally. If I delete the mailbox, messages get stuck again. We have a few thousand customers, so there are a few thousand groups called AllUsers@[customer.com], and each group has its own Service user as a member. I wonder if the categorizer runs out of steam trying to resolve the correct Service without a mailbox out of thousands. Although the UPN clearly states which one is which... -----Original Message----- From: Andrey Fyodorov Sent: Tuesday, October 22, 2002 10:25 AM To: Exchange Discussions Subject: RE: I just discovered a bug in Exchange 2000 crap...

We rely on global security groups that need to be mail-enabled, and our hosting architecture uses a windows account that's a member of these groups but is not mail-enabled. I do not want to mail-enable this account because we then would pay Exchange license fees for it to Microsoft (each customer has an account like that). -----Original Message----- From: Kevin Miller [mailto:Kevinm@;wlkmmas.org] Sent: Monday, October 21, 2002 6:10 PM To: Exchange Discussions Subject: RE: I just discovered a bug in Exchange 2000 Good job..

I have not been able to send mail to certain groups - messages would just get stuck in the Retry Queue "Awaiting Directory Lookup". This was also coincidental with IIS memory leak. I can't believe how simple the cause of the problem is! The groups that experience problems are mail-enabled global security groups AND some members of the group are not mail-enabled. That's all. I have been looking at all other things trying to solve the problem. I thought that for some reason there was a duplication of an SMTP address somewhere (actually that used to be another bug in earlier version of Exchange 2000) or maybe the LegacyExchangeDN was screwed up... I can't believe it did not occur to me to check all the group's members to see if any of them were somehow different. Now we do have a reason for having such mixed groups for customer provisioning methods.
