I have been reading prior posts regarding the 2 GB limit on PST file for
some versions of Outlook.

Is this unique to certain Outlook versions or does it pertain to the PST
file structure or both?

I am using Outlook 2007 but the PST file may have been created with an
earlier version of Outlook.

How can I tell about the PST file structure or which version created it?

In addition to the above, be aware that if you're still on a
FAT-formatted drive for some reason, the 2GB limit still applies
regardless of what version of Outlook or what PST version you're using.
