How to migrate PST to Office 365?

To migrate PST to Office 365 manually, you can use the Outlook application. First, open Outlook and go to File > Open & Export > Import/Export. Select Import from another program or file, then choose Outlook Data File (.pst). After that, browse and select your PST file, decide how duplicates should be handled, and click Next. Choose your Office 365 account as the destination, then click Finish to begin the import. Depending on the size of the PST file, this process may take some time.

However, the manual method can be time-consuming and prone to errors, especially when handling large PST files. A more efficient and reliable option is to use the BLR PST file converter tool. This tool streamlines the entire process by automatically migrating your PST files to Office 365 with just a few clicks. It eliminates the need for manual setup and minimizes the risk of data loss or corruption. With its advanced features, you can easily transfer emails, contacts, calendars, and more, ensuring a seamless migration experience.

  • If you want to upload PST files to Office 365 without using Outlook, there are a few efficient options available. The most common method is the Microsoft Network Upload approach, which is ideal for bulk or admin-driven migrations:

    • Network Upload Method:
      This method lets you upload PST files directly to Microsoft 365 cloud storage using the AzCopy tool, then map and import them to user mailboxes via the Microsoft 365 Compliance Center. You don’t need Outlook installed for this process. The steps include:

      • Get a Shared Access Signature (SAS) URL from the Compliance Center.

      • Use the AzCopy tool to upload your PST files to Microsoft’s Azure storage.

      • Prepare a PST mapping file to link each PST to the correct mailbox.

      • Create and start an import job in the Compliance Center, applying filters if needed.

      • Monitor the job until the import complete.

    • Third-Party Tools:
      If you prefer a more user-friendly or feature-rich solution, several professional tools allow you to upload PST files directly to Office 365. These tools often provide advanced filtering, incremental migration, and direct mapping to mailboxes, making large or complex migrations easier and more reliable.
