I installed Exchange server 2007 on a test server perfectly, but a week after it was taken offline by mistake without demoting from AD and without uninstalling exchange 2007, now whenever I install exchange 2007 on another server the other name of the old server shows in the console and everything points to the old one even though it not online. And of course nothing works because it doesn't exist. After I ran into that problem I removed exchange server 2007 and tried reinstalling and now I get the following message Initialize-ExchangeUniversalGroups. Can anyone help with this issue. The help is greatly appreciated.
