I am currently working with a very old Outlook PST file that is still in ANSI format, and it has started causing issues like size limitations and frequent errors. I recently learned that upgrading the file to Unicode PST format can fix these problems and support a much larger file size. However, I am not sure what the safest and most reliable method is to perform this upgrade. I have seen a few manual steps online, but I am worried about data loss or corruption during the conversion. Can anyone recommend the best working method to convert or upgrade an old ANSI PST file into Unicode format?
