I have set up and installed my own server using VMWare with Server 2008 and Server 2011 SBS, using Exchange 2010.
It's all running very smoothly considernig it's my first go at this kind of thing.
I have set up a number of email addresses in my Exchange as well as Distribution Groups.
I have a requirement for a Distribution Group "firstname.lastname@example.org" - but when I try to add this it fails, telling me that the email address already exists.
The trouble is I can't find it anywhere. It's not in my Recipient List, and not in my Distribution Groups list....
Can anyone give me some ideas of where this might be hiding? I will update with any information required.
