A practical method of moving old Outlook emails to a cloud-based mailbox is to import PST files. If you are migrating just one PST file or dealing with multiple mailboxes, taking the correct steps will help keep your email data in order and make the process easier to manage.

Check Your PST Files Before Importing

Before you start, find your PST files and ensure that they are accessible. Have a look at the emails, attachments, and folder structure that you want to transfer. When you have more than one PST file, sort them by user or mailbox so that you don't get confused during the import process.

Choose the Right PST Import Method

Microsoft 365 includes supported ways of importing PST files, such as using the network upload process or having the drive shipped when these options are available. Using the network upload method, administrators are able to upload PST files to Microsoft's specified Azure storage location and use an import mapping file to indicate which mailboxes should get the data.

When carrying out large-scale migrations, you should carefully plan the upload. Before you begin, check your available storage, your network speed, your mailbox permissions, and the Microsoft 365 import requirements.
