Migrating Thunderbird to an Office 365 account becomes simple and reliable when users try or download the BLR MBOX Converter. Thunderbird stores all emails in MBOX format, whereas Office 365 works on cloud-based mailboxes that do not support MBOX files directly. This creates a compatibility gap, and manual migration is not available. An advanced MBOX Converter fills this gap by providing a smooth, step-by-step migration path.

With the tool, you can load your data in two ways:

• Add MBOX Files Manually – Select individual MBOX files from the Thunderbird directory.
• Profile Mode – Automatically detect and load the entire Thunderbird profile with all folders and accounts.

After loading, the MBOX Converter allows users to export Thunderbird emails directly to Office 365. Just simply by entering Office 365 login details. The tool maintains folder structure, metadata, Unicode content, embedded images, and attachments during migration. It also ensures no emails are lost or duplicated. This application also makes the migration from Thunderbird to Office 365 fast, accurate, and user-friendly—even for non-technical users.
