Hi there,
Scenario: One Exchange 2007 server and one 2010 Exchange server co-existing. All mailboxes have been migrated off of 2007 to the 2010 server.
In some cases, when adding an account to Outlook, the only way to add the account is to initially use the 2007 server. Using the 2010 server at this time responds with an immediate resolution error.
If I use the 2007 server, the account will be added, and when I go in a look at the account settings in Outlook, the 2010 server is now listed. If I delete the account and re-add it, I can then use the 2010 server to add the account.
My question is: If I de-commission the 2007 server and at some point someone comes across the above problem, what is the work-around? I imagine that I could delete the user account, recreate it, and then attach the mailbox to this user account, but I'm hoping someone has some experience with this and has some ideas on the best way to deal with it.
Thanks in advance for your help.
Best,
Kim
