Import PST to Google Workspace: 2026 Secure Migration Guide

Why Do Users Import PST File to Google Workspace?

The PST file is also known as “Personal Storage Table.” Outlook by default uses the PST format to provide an output data file. This file stores emails, contacts, calendars, tasks, etc. However, this file format can be accessed only through Outlook. As a result, if someone wants to access that data, they need to have Outlook installed on their system. The points below explain why it’s essential to migrate PST file to Google Workspace.

• Easier Access: Users can open Gmail on any device, which allows users to access PST files without the Outlook application.
• Central Management: PST files can be accessed, maintained, and protected by admins from one place.
• Easier Searching: Users can search and find old messages in Gmail. This helps with legal audits faster.
• Cloud Storage: Everything is stored in Google’s cloud storage, so there are very low chances of data loss and file corruption. 
• Team Collaboration: Teams can access old mail in new accounts. This helps them keep records of different departments and staff easily.

How Can Users Import PST to Google Workspace?

There are various ways through which users can migrate their PST files to Google Workspace. However, manual methods depend on either Google or Outlook and are suitable if the user has a small number of PST files or has smaller-sized PST files. Before you start the migration, it’s good to back up your PST files. 

Method 1: Use GWMMO to Migrate PST to Google Workspace

GWMMO means “Google Workspace Migration for Microsoft Outlook.” It’s an official tool offered by Google. This allows users to import mail, calendar events, and contacts.

1. Firstly, log in to a Google Workspace account and go to settings. 
2. Then, activate IMAP access in the Forwarding and POP/IMAP section. 
3. After that, install the Google Workspace Migration tool available from the official website of Google.
4. When successfully installed, open the tool and log in to the destination Google Workspace account.
5. Now, select the Add option and then browse for the required PST file to import into Google Workspace.
6. Moreover, the admin can export all the data or only new data and then choose categories, such as emails, contacts, calendars, etc.
7. Finally, click Migrate and wait for some seconds for the migration.

Method 2: Use GWMME for Administrators

GWMME means “Google Workspace Migration for Microsoft Exchange.” It allows admins to import PST to Google Workspace for a large number of users. 

1. In the Google Admin Console, create a service account and enable the API. 
2. Now, authorise the Google Workspace Migration for Microsoft Exchange.
3. Categorise the PST files in a proper hierarchy with subfolders.
4. Download and install the GWMME from the official website of Google.
5. Open GWMME and choose the PST folder you want to migrate. 
6. Now, sign in to the destination Google Workspace account and authenticate it. 
7. Upload the CSV file, and then map the source and destination folders.
8. Start the migration and wait for the migration to be complete.

Method 3: Copy PST Folders to Gmail Through Outlook

This method doesn’t depend on any additional software. Therefore, an individual with a smaller number of files should migrate PST to Google Workspace.

1. Open Classic Outlook on your system.
2.  Go to File, then Add Account.
3. Enter the account credentials and click Connect to sign in.
4. Now, go to File and click Open and Export, then Open Outlook Data File.
5. Create a new folder under the Gmail account for the imported mail.
6. Select the required PST folders, then drag the corresponding folder to Gmail.
7. Let Outlook finish syncing to complete the migration process.

Limitations of Native Methods

Native methods are an ideal choice for small-scale migration. However, they are not ideal for users who want to import PST to G Suite in large quantities. Below are some limitations of native methods.

1. Large files take a long time because Outlook uploads items through a normal sync.
2. An interrupted sync can leave folders incomplete.
3. The Outlook copy method offers no filters, duplicate handling, or reports.
4. Each PST file needs separate handling, which is impractical for bulk work.
5. Outlook must be installed and licensed on the working computer.
6. Syncing large PST files takes longer compared to small PST files, which makes IMAP synchronisation slow.
7. The native method is only limited to mailboxes and can’t migrate contacts, calendars, tasks, etc.
8. Version rules can block the Google utilities completely.
