I need to recover some mails from a backed up OST file. Unfortunately, I deleted the corresponding IMAP mail account from Outlook. When I recreate the mail account and replace the created OST file with my backup I get the following error message:
The file {path}.ost cannot be accessed because it has been configured for use with a different mailbox.
How to solve this problem?
Please don't suggest a OST to PST tool unless you know it works. I tried numerous of those tools from dubious looking websites and none worked.
Please note: I am using Outlook 2013 Preview.

Unfortunately, there is no native way to recover the email. OSTs are linked to the account (and as you found out, account instance) that spawned them. Recovery is possible, but you will have to go to third party tools to get that. As this is a non-released version of Outlook, your luck there will likely be less than it would be if the Outlook version were released.
My company deals with OST reading as part of our line-of-business, and it is a very tricky problem.
Recommending a third party tool is out-of-scope of this site (and Stack Exchange generally).
