Upgrade PST file to latest and determine current version - how?

A few related questions relatet to Outlook PST files.

1) How do I determine in Outlook 2003 which type of PST file (2003 or prior) a PST file is?
2) Is Outlook 2007 same PST version as 2003?
3) Can I upgrade Outlook 2002 to 2003 (or even 2007 if exists) without dragging to new PST - want to maintain the numerous rules that have been created.
4) What is the maximum file size for a 2003 PST file on Windows XP?

Hello afflik1923,

1) On the Tools menu, click Options.
Click Mail Setup, and then click Data Files.
Click the data file you want to check, and then click Settings.
Check the Format field to see if it contains the string Personal Folders file or Personal Folders file (97-2002).

2) Yes, Outlook 2007 is same PST format as OL2003.
3) No, you cannot upgrade to OL2003 PST file format from OL2002 format without dragging to new PST.
4) Initial set size is ~20 GB.  By modifying the registry, you can set the size to ~33 TB.

Hope this helps!

GReat - excellent succinct answers.

Further to that I walways thoguht they very max an outlook file in Vista coudl be is 4GB. Therefore a file can only be 4gb big or something.

Is there any facts in my statement here or I am getting mixed up with something else?
No, there is no Vista limit of 4 GB.  That is something else.  Fat32 data format has a transfer limit of 4 GB.  NTFS format has not such limit.

I did not actually mean to say Vista in the posting before. I meant Outlook - Vista on the brain!

But from what you have said it would appear that as long as the system is formatted to NTFS it should not have a filesize limit (evenon XP)
