You can import PST files into Office 365 using several reliable methods, depending on the size of your data and your technical comfort level. Microsoft provides native options like the
Network Upload method (using Azure AzCopy) and
Outlook Import. Still, these can be time-consuming and complex, especially for large PST files or multiple mailboxes.
From my personal experience, manual methods worked only for small PST files and required extensive preparation—CSV mapping, permissions, and constant monitoring. Things got much easier when I switched to a professional approach. A dedicated tool from
BLR Tools allowed me to upload PST files directly into Office 365 mailboxes without worrying about file size limits, data loss, or folder mismatch.
A professional solution helps maintain email structure, attachments, metadata, and supports bulk PST imports. This makes it ideal for businesses, admins, or users who want a fast, secure, and hassle-free way to import PST files to Office 365 without technical complications.
