OK, I am going to reinstall my machine this weekend, one of the things I will be replacing is an illegal copy of Office 2003 for a legal copy of Office XP. I have used Office 2003 a lot, especially Outlook. Now you can use the export/import feature in XP and 2003, but there is a difference between these two types of Personal Folders files, according to MS Knowledge base article 839109, Office 2003 .pst files are stored in Unicode, while XP .pst files are based on ANSI. Now, you there is a guide on that same page, telling you how to convert the Unicode to ANSI by creating a new Personal folder based on ANSI storage and copying all items to that Personal Folder. But there is also a note on that same page, which explains that it is not possible to convert emails with Unicode characters in it to the ANSI format. But how can I check that? Also, is there a way to convert a Unicode email to ANSI email?
