Introduction

Want to import PST file to Airmail on Mac/Windows but do not know the correct way? We know, migrating email data from one platform to another can become a tough task if you do not have proper guidance, especially when dealing with file formats like PST that are supported by Microsoft Outlook only. So, if you’re planning to switch to Airmail, a popular email client for macOS and iOS. Then in this guide, you’ll know the best approaches to migrate PST to Airmail. Read this article in order to get the best solutions.

PST vs Airmail

A PST (Personal Storage Table) file is a Microsoft Outlook supported file format. It stores emails, contacts, calendars, and other mailbox data locally. Airmail, on the other hand, does not directly support PST files. It works with standard email protocols such as IMAP, POP3, and Exchange. This means that before your PST data can be accessed in Airmail, it must first be converted or imported into a compatible email account.
