Quick Answer: You can import PST files into Gmail using three popular methods available on the most platforms.

1. Google Workspace Migration for Microsoft Outlook (GWMMO): The official Google Migration Tool.

2. Outlook IMAP Synchronisation: Setup Gmail in Outlook and migrate PST data via Synchronisation.

3. PST to Gmail Migration Tool: Direct method to import PST to Gmail without Outlook.

Both GWMMO and Outlook can work well with small PST files. However, for large PST files (10 GB or more) a dedicated PST to Gmail migration tool is often considered to avoid synchronization issues.

What is a PST File?

PST is a Personal storage file format of Microsoft Outlook to store mailbox data information locally. Your PST file may contain emails, contacts, calendars, Notes, Tasks, journal entries and any other data in your email account. Usually, PST file is created by users to archive old emails or to maintain complete mailbox backup. However, accessing PST files only requires Outlook and creates dependency of having Outlook to read PST files. Thus, importing PST files into Gmail will let you access your PST email data anywhere and at anytime.

My Real-World PST to Gmail Migration Experience
While searching solutions for PST to Gmail migration problems, I found a user query on Reddit discussion forum. A user asked:

pst to gmail query

The user has three major issues;

  • The administrator of their organization has turned off adding another email account in Outlook.
  • Manually forwarding thousands of emails is not possible.
  • Google’s GWMMO Tool is unsupported on ChromeOS.

In this case, the other described methods above are difficult or impossible to use. It’s so because the user has mailbox data in a PST file but does not have the environment to use Outlook-based migration tools.

A direct PST to Gmail migration solution like Advik PST File Converter is beneficial for users in this type of similar situations as it reads the PST file independently and uploads mailbox data directly to Gmail without configuring Outlook account. This eliminate the need to depend on Outlook synchronisation, administrator permissions or GWMMO compatibility issues.

Why Import PST to Gmail?

There are several benefits of migrating Outlook PST file into Gmail. Some of them are:

  • Remote Access: Data stored in PST files can be accessed only through MS Outlook. Migrating Outlook PST data to Gmail allows access to emails and other mailbox data on any device from anywhere, rather than relying on Outlook.
  • Backup: PST files stored locally that can be lost due to system crash, hardware failure, accidental deletion, corruption and more. If user moves PST to Gmail, they can securely store their data in the cloud.
  • Advanced Search: Sometimes finding old emails in a large PST file can be difficult. Gmail provides advanced search capabilities to quickly find out emails.
  • Integration with Google Services: Gmail is integrated with various Google services like Google Drive, Docs, Sheets, Meet, Calendar etc. With a Gmail account user can also take benefits of these services.
