Outlook 2013

I am trying to export Outlook emails to an Outlook data file(.pst) which I have done many times before but it asks for the password which I have forgotten. How do I change the password?

If you're seeing this (or similar)

you're not being asked to enter an existing password. You're simply being invited to use one for your new .pst file. If you don't want to password protect it, just leave the fields blank.

If you've already got a password protected .pst file, use Nirsoft's free utility to find out what it is:

Thanks very much. It's the second of those. I'll try it and hope it works.
