Migrate OST File to Office 365 Tool - PST Migrator

[Ryancooper]

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.

To simplify this process, you can use the Cigati OST to Office 365 Migration Tool, which offers a direct and efficient way to migrate OST files to Office 365 without any complex steps. This tool allows you to upload orphaned or corrupted OST files, ensuring a secure migration while maintaining folder hierarchy and metadata integrity.

When migrating an OST file to Office 365, the best and most reliable method is to use a professional OST-to-PST converter that also supports direct Office 365 migration. OST files are tied to specific Outlook profiles and server accounts, so they can’t be uploaded directly into Office 365. Native Microsoft options only work if the original mailbox is still connected, which isn’t always the case with orphaned or corrupted OST files.

A dedicated OST to PST converter first extracts all mailbox data — including emails, attachments, contacts, calendars, and metadata — and saves it in a usable PST file. From my personal experience, using a trusted solution from BLR Tools made the migration much smoother than manual exports. After converting the OST to PST, the tool securely uploads the PST into the Office 365 mailbox, preserving folder structure and data accuracy. This professional approach saves time, avoids errors, and ensures complete data integrity throughout the migration process.
