Yes. Outlook 2021 can import and read your Office 2013 PST file, which contains all your saved emails, calendar events, and contact address books.
Should I wait for a newer Office version like Office 2024 to upgrade?
If your current Office 2013 suite meets your everyday needs, you could theoretically wait. However, Office 2013 has reached its end of support, meaning it no longer receives crucial security updates.
