Easiest Ways to Import Outlook PST Files into Microsoft 365

Importing PST files into Microsoft 365 is essential for organizations moving legacy Outlook data into the cloud, ensuring compliance, accessibility, and data protection. You can use Microsoft’s free methods—Network Upload, Drive Shipping, or manual Outlook import—or opt for third‑party tools for large, complex migrations.

Why Import PST to Microsoft 365?

Data protection: PST files stored locally are fragile and prone to corruption. Migrating them ensures high availability and backup in Exchange Online.

Compliance: Microsoft 365 offers retention policies, litigation hold, and eDiscovery, making imported data legally defensible.

Accessibility: Once in the cloud, emails are accessible across devices, improving productivity.

Centralization: Consolidates scattered PSTs into managed mailboxes, reducing IT overhead.

Manual Methods to Import PST to Microsoft 365

There are several methods that Microsoft has designed to allow for the importing of PST files.

1. Network Upload Method

With this method, PST files are uploaded to Azure Storage and then imported into Microsoft 365 mailboxes using the Microsoft Purview compliance portal.

Steps

1. Create Microsoft 365 import jobs for PST files.
2. Install the AzCopy utility.
3. Transfer PST files to Azure Storage.
4. Create a CSV file for mapping.
5. Initiate import jobs for PST files.
6. Finish the import to Microsoft 365 and monitor for any issues.

Drawbacks

• Technical knowledge is a must.
• Many lengthy configurations.
• Large scale migrations take a long time.
• Complex mapping of mailboxes is required.

2. Drive Shipping Method

Here, PST files are saved on hard drives, encrypted, and sent to Microsoft data centers.

Drawbacks

• Higher shipping costs.
• Centered on older methods, so impractical.
