How to Convert Outlook PST Files to ICS File Format?

What are PST and ICS Files?

Think of PST as a digital folder where Outlook keeps all its mailbox data. PST or Personal Storage Table stores copies of calendar events, messages, contacts, notes, etc. within Outlook. Also, when sharing Outlook mailbox data or moving to a different platform, you need to work with PST files.

On the other hand, an ICS file refers to the iCalendar file. It is solely used to share calendar information with others and allows to open calendars on different applications. You can open .ics files using Outlook, Google Calendar, Apple Calendar applications, and other emails. It is used to send details about meetings, appointments, and special dates and describe events.
