Hi,
I am having an issue with the migration of mailboxes from our Exchange 2010 server to our Exchange 2013 sever. I moved the mailbox from EX2010 to EX2013 using the EAC on the EX2013 server. The user moved was using Outlook 2010 to view and manage their mailbox with no issue before the move. When the user tries to open Outlook after the move they are getting the following message:
"Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)"
I have read through various posts and suggestions but so far nothing has helped. Our setup is:
Exchange 2013 installed on Windows Server 2012
Exchange 2010 installed on Windows Server 2008 R2 which is a virtual server running on the Exchange 2013 physical server
Our internal AD is different from our external DNS. We also host a copy of our external DNS records internally which point to internal IP addresses.
So far I have tried the following with no luck:
- Removed the .ost files and restarted Outlook
- Removed the mail profile and recreated
- Tried restarting the RPC Client Access Service on the Exchange 2013 server
- Created a new test user and added a mailbox to the Exchange 2013 server
- Tried to manually configure the Exchange settings for the Outlook client. When I did this it won't accept the FQDN of the Exchange 2013 server but when I enter the FQDN of the Exchange 2010 server it automatically changes it to the FQDN of the Exchange 2013
server. It looks like it knows the mailbox is on the Exchange 2013 server but then won't let me open it.
Can anyone help or point me in the right direction as I want to migrate these mailboxes asap so that I can retire the Exchange 2010 server.
Thanks
