User has sent an email (meeting schedule) to a Group "Test 1". "Test 2" is also a group and is a member of group "Test 1" has not received the email. "Test 2" group members do have email enabled but still they have not received the email sent to group "Test 1". we have Windows Server 2003 AD Domain and Exchange Server 2003 SP2 Messaging Organization. These groups consist of some 74 members/users and when we ran a message trace we just found out that the actual email was only delivered to 50 odd users and there a no double specifications in these lists and has already been validated. All the Receiving Options and Send Options/settings such as limits and rights have been validated on the user, organizaer and DL and are Ok. user states the issue as intermittent. please advice...

When you send to the child groups individually does the message reach the recipients? Do you have a maximum number of message recipients configued in your organization?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Make sure all groups root and nested are set as universal groups.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

How many domains are there in your AD forest? Do all of the groups have a Universal scope? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hello! Thank You All for your responses. When we send an email to the child DL seperately, it is received/delivered properly. and the problems seems to be more with Meeting Invitiations or the Calendar Items and normal messages seems to have delivered properly. They are Security Groups and the Scope is set to Global for both. We have two domains (parent and child) in a single active directory forest. Exchange Organization is hosted in child domain. parent is just a simple root for administrative purposes. Regards, Bala Krishna.

Try changing all the groups to Universal groups.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

That can be a problem. >We have two domains (parent and child) in a single active directory forest. Exchange Organization is hosted in child domain. parent is just a simple root for administrative purposes. Are both domains in the same Active Directory Site? Are all the DC also GCs? If so, your Exchange server can use any GC when it expands a group. If it picks the GC in the domain that doesn't "own" the group, and the group doesn't have a Universal scope, then the GC doesn't have a populated "members" property for the group. Make ALL your mail-enabled groups have a Unversal scope and each GC will have a populated "members" property for each grop. Then it doesn't matter which GC is used when the group is expanded. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

ok. will change the group scope to universal. will verify and post you the test results.
