SBS 2003 migration to Exchange2010 went wrong & now cant access mailboxes

Hi Experts,
We have a bit of a sticky situation and urgently would like some advice on the following please….

Over this weekend we tried to migrate our physical SBS 2003 to 2 Virtual servers….one with Exchange 2010 running on server 2008 server and one domain controller again running Windows server 2008.

The project seemed to be going all smoothly with all mailboxes being transferred over to Exchange 2010. However during the final stage of decommissioning the SBS 2003 server some mailboxes (about 10) were oddly lost. We couldn’t see the mailboxes on either the SBS 2003 server or the Exchange 2010 server despite spending a fair amount of time looking for them. And as we didn’t really have enough time just now to re-do all the migration steps we thought it would be best to de-promo the Server 2008 DC, close both the VM’s and then restore a backup image of SBS 2003 using a Symantec system recovery image of SBS 2003.

The backup image was restored fine & we can access shared drives but the problem we have now is no users can view there mailbox in outlook 2010 as outlook just hangs and when trying to access there mailbox via OWA it doesn’t display the regular OWA screen it just prompts for a user name and password but when we enter the credential’s it says HTTP/1.1 401 Unauthorized. On the SBS server we can open Exchange manager and see all the users’ mailboxes, but when we open a users properties we cannot see any exchange related tabs.

The system recovery image of the SBS 2003 server was taken prior to installing Exchange 2010 but the virtual DC was added as a primary DC to the existing AD domain. We don’t understand why we now cant access the user mailboxes on SBS 2003

Any help on this would be appreciated. We have backup images of the SBS 2003 server every evening so as last resort could try using an older image but we really want to ensure users have the most up to date copy of their email as possible.

Thanks

Was the certs applied to the new server for OWA ?
Was the Outlook profiles re-created after migration ?
Is the new server a SBS as well ?

Hi Rancy, Yes certificate was applied to new Exchange 2010 server for OWA

We used autodiscover to let outlook 2010 automatically pickup the new Exchange server (we only powered on & tested on 5 client computers)

No the new virtual servers were: Server 2008 with Exchange 2010 + another server with server 2008 setup as a domain controller, DNS and DHCP.

The virtual servers are currently powered down and we just have the orginal phsical SBS 2003 server running with the accessing mailbox issues

Does this info help?

Is the DC a GC as well ?
Where are the FSMO roles ?
If you stop the Microsoft services on the SBS ... i guess everything's affected ? Try running EXBPA at the same time from Exchange 2010 and check for any errors apart from Services stopped on SBS 2003.

The virtual server 2008 DC is also a GC yes - (currently powered of)
the FSMO roles are all currently on the SBS 2003 server - (we never got to the stage of transffering these)

The microsoft Exchange services stop and start fine if thats what you mean? - we can browse the network fine, so dont think everything been affected. Do you mean Microsoft Exchange Best Practices Analyzer? - we have the Exchange 2010 virtual server stopped and not connected to the network and this doesnt have all the user mailboxes.

Please can you clarify?

were concerned about re-powering up exchange 2010 now as for now would like to just get SBS 2003 fixed from the backup image if possible.
