I am stuck with an old Outlook ANSI PST file that has reached its size limit and is now causing performance issues. I want to move all data into a Unicode PST file to avoid corruption and support more storage. Can anyone suggest the best and safest method to convert an ANSI PST file to Unicode in Outlook?

If you're using data from an older Outlook version (such as Outlook 2002 or earlier), your PST file will be in ANSI format. The biggest drawback of ANSI PST is its 2GB size limit. This limit can cause the file to become corrupted quickly and cause it to not work properly in newer Outlook versions. Therefore, converting an ANSI PST to a Unicode PST file is essential for better performance and larger file size support. Softaken PST Upgrade Software is a reliable and easy-to-use tool that safely upgrades older ANSI PST files to the Unicode PST format.
