What Clients Say

The Office 365 to Outlook Converter tool works wonders for me. It is a great and easy-to-use tool that even a non-technical person can understand. It has a very simple interface and can extract unlimited .eml messages from O365 email folders. I tried Office 365 export EML and successfully migrated a bunch of emails without data loss.

Toni Wallace, Croatia

There is a lot to be said about Office 365 archive to PST tool. It is one of the best in backing up mailbox data for multiple users in a single go. It saved us a lot of time by providing multiple options to filter mailbox data. We reduced time and efforts by filtering backups based on date, user and mailbox items. The O365 to PST export tool is an exceptional software.

Clifton Strickland, Venezuela

Each time I tried to open my Office 365 Mail App from my on tablet, it usually did not respond. Either it took hours to open up and took all memory on my Android device or simply hung mid-way. I used the O365 Backup tool to archive important conversations and deleted them from the server. This freed up a lot of space on my device to do other tasks. Now my emails are saved on my external drive and Office 365 works great on my tablet. Thank you!

Using the O365 to PST Converter has brought us great benefits. All the attachments and email formatting were kept intact during transfer.
