User Query: I have a PST file exported from my old Outlook account. And now I want to move all emails, contacts, and other data to my Gmail account. What is the easiest and safest way to import PST file to Gmail without losing anything?
Summary: A PST file (Personal Storage Table) is created by Microsoft Outlook to store emails, contacts, calendars, tasks, and other mailbox data locally on a computer. But PST files are not supported by Gmail or any web-based email service directly. However, Gmail does not provide a direct “Upload PST” button. That’s why users look for a reliable way to import Outlook PST to Gmail without corruption or data loss. In this blog, we will discuss a simple manual method and a professional DRS Softech PST File Converter for a hassle-free conversion.
Real-Life Scenario:
Rohit had a 6GB PST file from his old Outlook account that stored years of business emails and contacts. After switching to Gmail, he tried using the manual Outlook IMAP method. But it was taking hours and kept getting stuck. He didn’t want to lose important messages. So he used a professional PST to Gmail migration tool that uploaded the entire PST file directly to his Gmail account in one go—without errors.
Direct Solution to Import PST File to Gmail
- Download and install the DRS Softech PST File Converter.
- Pick: Select Files or Select Folder to add your PST files.
- You can preview and select the PST emails to convert.
- Choose: Gmail as the Saving Format & enter its details to Sign In.
- Lastly, use advanced features/filters and click Convert.
Method 01: Upload PST File to Gmail Manually using GWMMO
Google provides a free utility called GWMMO (Google Workspace Migration for Microsoft Outlook). It works only if you use a Google Workspace account, not a personal Gmail ID. Steps to use it:
- Firstly, enable IMAP in Gmail settings.
- Now, download and install the GWMMO tool from Google.
- Then, log in with your Gmail/Workspace account.
- After that, browse and select your PST file.
- Further, choose what you want to import (emails, contacts, calendar, etc.).
- In the end, click Start Migration and wait for processing.
Important Note:
- Not available for normal @gmail.com accounts.
- Slow for large PST files (above 2GB).
Method 02: Import PST File to Gmail Using Outlook IMAP Settings
This method requires Outlook and Gmail IMAP configuration. Here is how you can perform it:
- Firstly, open Gmail and click Settings → Enable IMAP.
- Then, generate App Password (if 2-step verification is ON).
- Open Outlook → Add Gmail account using IMAP.
- Drag and drop PST emails into the Gmail mailbox folder in Outlook.
- In the end, wait until Outlook syncs data to Gmail servers.
Limitations of the Manual Method
- You need to set up Outlook, enable IMAP, configure Gmail, and upload data manually.
- IMAP syncing often gets stuck, stops midway, or duplicates emails, especially with large or corrupted PST files.
- Attachments, folder structure, and metadata may not migrate properly.
- Involves multiple steps, setting changes, and troubleshooting—difficult for beginners.
- Additionally, you can’t filter emails by date, folder, or size. Everything gets migrated, even unwanted emails.
