Quick Answer: Opening or uploading a PST file to Gmail is not possible since PST is a proprietary format developed by Microsoft, and thus Gmail’s servers do not recognize it. There are still reliable ways to import PST to Gmail, whether you have Microsoft Outlook installed or not. You can either use Outlook’s own “add account” feature to import Gmail account in Outlook and drag and drop the PST file into the Gmail folder, or use GWMMO tool if you have a business Gmail account. Therefore, if you want to directly migrate a PST file to Gmail, then use a dedicated PST to Gmail migration tool. The tool provides more control over the entire process and provides an easy and time-saving migration.

Method 2: Migrate PST to Gmail Using GWMMO Tool

Tips:

  • Control File Sizes: Large PST files take longer to be uploaded and are more prone to resulting in network errors. If feasible, consider splitting them into smaller files.
  • Network Reliability: Ensure that your connection remains strong and stable throughout the migration process.
  • Data Protection: Always make a copy of your PST file before starting migration.

Note: Usually, manual migration of large volumes of data suffers from the limitations of free software and inexperienced users often use special software for the task.

Limitations of Available Manual Techniques

  • Most of the free solutions work only when you have already installed Outlook on your system. If you do not have Outlook installed on your system, the free technique to import PST to Gmail will not work.
  • Manual technique works well for the PST file size of majorly 10 GB; above this, there is a likelihood that your migration process may slow down or completely fail in the middle.
  • This free tool and DIY technique does not guarantee that the folder structure of the data will be preserved after importing the PST to Gmail.
  • Manual solutions do not provide any dedicated support if anything goes wrong during the saving process or overcome a query.
  • Requires the need for Outlook installation for the account configuration process, which is not always reliable.
