Introduction
Looking for an easy way to import PST files into an Office 365 mailbox? Many Outlook users keep their emails, contacts, calendars, and other mailbox items in PST files and later need to move them to Microsoft 365 for better accessibility and cloud storage. Since the migration process can be confusing, especially for large PST files, choosing the right approach is important. In this guide, you’ll learn what a PST file is, why users migrate PST data to Office 365, the challenges of manual methods, and a reliable way to complete the migration without affecting your mailbox data.
What is a PST file?
A PST (Personal Storage Table) file is a data file created by Microsoft Outlook to store mailbox information locally on a computer. It is commonly used with POP accounts, archived mailboxes, or exported Outlook data.
A PST file can store:
- Email messages
- Contacts
- calendar events
- Tasks
- Notes
- Journal entries
- Attachments
- Folder hierarchy
Because all mailbox information is stored in a single file, PST files are widely used for email backup, archiving, and transferring Outlook data between systems.
