If you’re using an older version of Outlook, your PST files are probably in the ANSI format, which has a small storage limit. To overcome this, you can easily convert them to the UNICODE format using the SysInfo PST Upgrade & Downgrade Tool. This tool upgrades your PST files so you can use them in newer Outlook versions without worrying about space limitations or data corruption. It keeps all your emails, contacts, and folders just as they were while expanding the available storage space. It’s a simple and secure way to make your Outlook data compatible with modern versions.
