The best way to upload PST files to Office 365 depends on the size of your data and how comfortable you are with the process.
For small PST files, you can use Microsoft Outlook. Add your Office 365 account to Outlook and import the PST file using the Import/Export option. However, from experience, this method is slow and not suitable for large or multiple files.
Another option is the Office 365 Import Service, which allows you to upload PST files to the cloud and map them to user mailboxes. While effective, it can be complex and time-consuming for beginners.
The easiest and most efficient method is to use a professional PST Converter. These tools allow you to upload PST files directly to Office 365 mailboxes in bulk while preserving emails, attachments, and folder structure.
Using BLR Tools, the process becomes simple and reliable. It supports large PST files, reduces manual effort, and ensures accurate migration without data loss.
Overall, for quick and hassle-free results, using a reliable tool is the best way to upload PST files to Office 365.

    If you are facing Outlook freezing issues during migration, I would suggest avoiding the manual import method for large PST files. I had a similar problem where Outlook kept hanging, and some attachments were not imported correctly. What worked better for me was using the CloudXena PST to Office 365 Migration Tool because it directly migrates PST files into Office 365 without requiring Outlook installation.
    You just need to install the software, add your PST files, enter Office 365 credentials, and select the target mailbox, such as primary, archive, or shared mailbox. The tool preserves folder structure, attachments, metadata, and email formatting exactly as stored in the original file. It also supports bulk migration, which saves a lot of time if you have multiple PST files.
    Another useful thing is that it supports several file formats, including PST, EML, MSG, MBOX, PDF, and HTML, along with migration support for different email clients and cloud platforms. I would also recommend using the duplicate removal feature because manual imports often create repeated emails. If you want to test before purchasing, the demo version lets you preview mailbox data and migrate a limited emails safely.
