After deleting an email account and recreating it, I have ended up with 2 pst files for the same email address and want to merge them.

The current situation is:

* I have one folder A linked to a pst file which is contains the last two weeks mail history. This file and folder receive and send new emails. The folder cannot be closed as far as I can see.
* The other folder B is linked to another pst file and contains everything up to yesterday. This folder cannot be closed either.

If I import B into a or move items form B into A:

• I cannot close the folder and file to remove it from Outlook
• There is risk of two weeks duplicates

Any idea how to merge A and B?

I am surprised Outlook is so inflexible as it appears to be impossible to link a pst file to a user chosen email account. Or am I missing something?
