User Query:<\/em><\/strong> “I’m the Microsoft 365 admin for our company & I need to import PST to Office 365 for around 100 users. Microsoft Purview supports Network Upload, but the AzCopy and CSV mapping setup looks like a lot of work. Has anyone used the built-in method for a large migration, or is a third-party tool the better option?<\/em><\/p>\n<\/div>\n

If you manage a Microsoft 365 tenant, you’ve probably been here. A few PST files are easy. A few hundred, scattered across laptops, file servers and old backup drives, are a project of their own.<\/p>\n

This guide covers how to import PST files to Office 365 in bulk, where each method works, where it falls apart, and which one fits your situation.<\/p>\n
