How to Upgrade an Old PST File to the Latest Outlook Format?

[Gloriaustin01]

I have an old PST file that was created in an earlier version of Outlook (possibly 2002 or earlier), and I believe its in the ANSI format. I need to upgrade or convert it to the newer Unicode format so I can use it with modern versions of Outlook, like 2016.

Is there a safe and reliable way to upgrade a PST file without losing any emails, contacts, or folders?

If you have an old Outlook PST (Personal Storage Table) file that you want to use in newer Outlook versions (such as Outlook 2016, 2019, or Microsoft 365), you need to upgrade the file to the latest format. Older versions are in ANSI format, while newer versions use the Unicode format.

What is the difference between ANSI and Unicode?
ANSI PST file: Maximum 2 GB size limit, used in older Outlook versions (Outlook 2002 and earlier).
Unicode PST file: Supports larger sizes (20 GB or more), and is used in all versions after Outlook 2003.
