I have used Outlook XP (2002 SP3) under WinXP on desktop PC for 8 years.
Recently, I acquired a Win7 Netbook installed with Office 2010 Pro. I copied the Outlook 2002 PST on PC to the Netbook as the data file for Outlook 2010. Outlook 2010 open this 2002 PST file with no problem.
I then copied THIS Outlook 2010 PST file back to WinXP PC and used Outlook 2002 to open it. Outlook 2002 open it with no problem either.
It seems that I can use the same PST in Outlook 2002 or Outlook 2010 as long the size of PST is not over 2GB. Since my Netbook is used only when I am on the road, if this is true, I don’t need to spend money in upgrading the Office 2002 Pro to Office 2010 Pro on my WinXP PC.
O.K. here is my question. Am I making wrong conclusion on my experience in moving the PST file between Outlook 2002 and Outlook 2010? Is there any other possible hidden problem may occur?
