How do you import PST files for 500+ users into Office 365?

For 500+ users, most admins don’t import PST files manually because it becomes extremely difficult to track everything. The common approach is to use a bulk migration tool that can process multiple PST files together and upload them directly into Microsoft 365 mailboxes.

Many IT teams use SysInfo PST to Office 365 Migration Tool because it supports batch migration and helps keep emails, attachments, contacts, and folder hierarchy properly organized. Usually, admins migrate users in smaller groups to monitor progress more easily and avoid server overload during large migrations.

If you want to import PST files into Office 365 without manual complications you can use the Softaken PST to Office 365 Importer Software. I used this solution when migrating old Outlook archive files to Microsoft 365 mailboxes and the process was simple. The software securely uploads PST emails, contacts, calendars and attachments directly into Office 365 accounts without changing the original folder structure. It also supports bulk PST migration which saves a lot of time for business users. You need to add the PST file, enter Office 365 login credentials, preview mailbox data and start the import process. It works with all Outlook versions and provides accurate migration results with less effort.
