Ambiel Reyes, Austin, asked

A few months back, our firm switched email vendors. Before the change, the employees used Outlook, and there are 40 old PST files stored in my shared drive. Nobody can access these files without Outlook. The compliance team needs these PST files to be archived in a PDF format with all their attachments intact. Since the deadline provided is going to hit next week only, what’s the most feasible solution to effectively convert Outlook PST file to PDF without any loss of integrity?

Summary: Enterprises often deal with large amounts of confidential and crucial data at the same time. As a result, it becomes essential for them to keep an archive of this data. They choose PDF format for this, as it is the most widely supported format outside Outlook. Thus, once an individual or large-scale firm performs this conversion, they can save their Outlook emails, attachments, contacts, and calendars. The easier accessibility and portability lead Outlook users to use manual methods or the Aryson PST Converter to accomplish this conversion. Read this blog to the end to get all your conversion-related queries answered.
