Try the GainTools Outlook Extractor tool. It has made this task very easy. This tool directly scans the PST file and asks you what to extract ā mails, attachments, contacts, calendars, etc. You can select whatever you want, and it is saved in different folders or formats ā like MSG, VCF, ICS or just attachments. The best thing I found is that it opens the PST file even without Outlook. And even if the file is large, its performance remains fast. Apart from this, this tool is compatible with all versions of Windows, whether you are working on Windows 11, 10, 8.1, 8 or 7. It also comes with a free trial version, so you can test it first.
