Limit of Outlook strage capacity encountered!

[ARiley]

Running Outlook 2010 under XP I have today received two different error messages. One informed me that I had exceeded my Outlook.pst size and the other informed me that I was on the point of exceeding my Sent Folder size (10793 entries). I know that Outlook 2003 allows for larger files but cannot find how to do this using online Help. I've looked through a few hundred Forum entries but none dealt with this issue.


Please could someone point me in the right direction?
Next question is: having sorted this problem and backed the new Outlook file up, do I have to do anything special if I want to load it onto another Windows 7 system which currently uses a "small" Outlook.pst file?
All advice gratefully received.
