I recently created a distribution group on my Exchange 2003 server. When I send an email to this group to test it bounces back. If I delete the group and create it again I get the same result. If I create a different group with a different name it works just fine but if I go back the name I want the group doesn't work. I have tried variations of the name, having a period in between the names and the group works but if I take out the period and make it one word the email does not work. I'm baffled. I thought that maybe someone has an alias of that name in their emails but when I do a search that name does not come up. What is wrong? How do I find out what is wrong? I have created many groups and this is the first where I am having this problem. I would use a different name but managment wants to use that name so I am stuck.
