Wonder if anyone can help me, here is a little bit of background info on network.
I currently have a Server 2003 DC & Exchange 2003 on my server, we are in the process of moving over to Server 2008 R2 & Exchange 2010. I have added the new 2008 box onto the 2003 domain. We did a DC promo on the 2008 server.
Once restarted the server and logged back onto the domain some of the exchange features have stopped working when we access the Management console, when we try access the organizational mailboxes it says "access is denied" the client access feature is missing completely. We are able to see the 2003 mailboxes in the management console but cant access or move the mailboxes,when we try access the mailboxes its giving us a error about not able to contact the info store on the 2003 exchange even though we can see the mailboxes.
We have established that this problem is due to permissions. We have attended to create a seperate username for the 2008 server within the 2003 domain but are unsure what groups we need to add the user too, we have added the user to Organization Management group and unsure what other groups to add the 2008 user too inorder to fix the permissions problem.
Help with greatfully be appreciated.
