Migrating an OST file to Office 365 manually can be a complex process, as OST files are tied to a specific Outlook profile and cannot be imported directly. The manual process involves converting the OST file to PST using Outlook’s Import/Export feature. Then, you need to upload the PST file to Office 365 using Network Upload or Drive Shipping, which requires technical expertise and PowerShell commands. This method has several challenges, including data loss risk, file corruption, and the inability to migrate orphaned or inaccessible OST files.
