As before, make sure the new group scope is set to Universal? Microsoft recommends that all groups you create for Exchange Distribution List/Group purposes should be Universal. If it is universal and are still having the problem then crank up diagnostic logging for MSExchangeTransport Categorizer on the server that expanded the distribution list.
The Microsoft article I referenced previously on troubleshooting distribution groups - http://support.microsoft.com/kb/839949 - talks about why it is important to use Universal groups. Here is an excerpt from the article that includes this recommendation. "Distribution groups and global catalog servers The type of distribution groups that you use is an important consideration. Membership of global group objects is replicated to every domain controller in a forest. However, the membership of global groups can only be visible from domain controllers or global catalogs that are located in the same domain as the group. Only universal group memberships are replicated across all domains to all global catalog servers in the forest. Microsoft always recommends using universal distribution groups for mail distribution in a multi-domain environment. " Hope that helps, Peter Dahl. -----Original Message----- From: Didtel, Larry [mailto:larry.did...@stemilt.com] Sent: Wednesday, December 09, 2009 5:41 PM To: MS-Exchange Admin Issues Subject: Re: outside email to dist group missing 1 person I removed and added the user back.
