Last month, I migrated an organization from a single SBS2003 server to Server 2008 and Exchange 2010. At the end of the project, and just before completion, the old server physically died. Their backups were hosed and we have no way of getting it back online. This happened before I was able to decommission it. I had already transferred all the fsmo roles, moved all mailboxes and public folders but had not removed the server from the organization. I had to use adsiedit to and the ntdsutility to remove the failed dc.
Everything seems to be working ok on the new system with just a few exception. When I collect organizational health, it still shows there are two exchange servers, a 2010 and a 2003. Occasionally, as I pour through settings, I keep seeing references to the 2003 server when asked to select one for any given role. Also, I cannot get Outlook to sync the offline address book. Everyone is getting this error:
9:18:18 Microsoft Exchange offline address book
9:18:18 Not downloading Offline address book files. A server (URL) could not be located.
I deleted the old offline address book and created a new one. Made sure it was the default oab for each database. The ExchangeOAB directory shows the correct address book with an oab.xml file and it is listed under the OAB virtual directory in IIS. I can say that i went to https://ourdomain.com/OAB
and it prompted for a login, but when I logged in got an error that I didn't have permission to view it. Though I am not sure if I am even supposed to be able to browse it that way, I thought I would mention it.
So, two questions. Can anyone tell me how to get the OAB working and how do I remove a failed exchange server from the exchange organization so it will no longer be referenced?
