Migrating from on-premises environments to the cloud can significantly boost your business productivity as it has many facilities, including an enterprise-level email server. But after subscribing to Microsoft 365, many end-users often have to migrate emails from Outlook on their desktop to Microsoft 365 mailbox. Here, we’ll jaunt you through both manual and automation methods to help you import PST files to Microsoft 365 mailboxes.

How to Migrate Outlook Emails to Microsoft 365, Manually

For importing PST files manually to the Microsoft 365 mailbox or performing mailbox migration to Microsoft 365, we’ll first need to configure Microsoft 365 account in MS Outlook. Then, follow the steps below:

1. Click the File tab, click Open & Export, and select Import/Export.
   
2. Select Import from another program in the Import and Export wizard and click Next.
   
3. Select Outlook Data File (.pst) and click Next.
   
4. Browse for the Outlook PST data file, select it and click Next.
   
5. Set Options according to your preference and click Next.
   
   Note: If the PST file is password-protected, enter the password and unlock it, click OK.
6. Choose the Import items to the same folder in the option and select the Microsoft 365 mailbox, Click Finish.
   

That’s it! The manual method is way short, and there is nothing to worry about except the file size and the chances of data loss during the process. However, there are two more methods from Microsoft, which can be used to import PST files to Microsoft 365 mailboxes. Let’s have a close look at those methods.

A. Network Upload Method to Import PST to Microsoft 365

The Network Upload method is a great way to import PST data to Microsoft 365. It allows administrators to import their entire PST data to Microsoft 365 using the Azure AzCopy tool. But, keep in mind that the PST file should be stored on a file server or shared folder in your organization before migrating it to Microsoft 365. The steps involved in the Network upload method are:

1. Copying the SAS URL & Installing Azure AzCopy tool
2. Uploading PST file to Microsoft 365
3. Creating the PST Import mapping file
4. Creating a PST Import job in Microsoft 365
5. Filtering data and running the PST import job

This method allows you to export one PST file at a time; if you want to export bulk PST files to Microsoft 365, then you will have to repeat the process from the 2nd step to the 6th step or use a CSV file.

B. Use Drive Shipping to Import PST to Microsoft 365

Drive Shipping is another way to import PST data to Microsoft 365, which works by using a Secure storage key and PST Import Tool. In this method, you will have to copy your PST data to a hard drive and then ship it to one of the physical locations of Microsoft 365. The steps involved in the Drive Shipping method are:

1. Downloading the secure storage key and PST Import tool
2. Copying PST data to the hard drive
3. Creating a PST Import mapping file
4. Creating a PST Import job in Microsoft 365
5. Shipping hard drive to Microsoft
6. Filtering the data and starting the import job

The drawbacks of this method are that it takes 1-2 weeks to import the PST data to Microsoft 365, and every organization cannot wait for such a long period if there is an urgency of uploading PST to Microsoft 365 and the method is not free at all.

If organizations have to import PST files to multiple Microsoft 365 mailboxes, it would be a pain for Exchange administrators.

Both Network Upload and Drive Shipping methods are highly technical in nature.

All these shortcomings in the manual procedures are a wake-up call for the users, and then they to use automated tools to import PST files to one or more Microsoft 365 mailboxes.
