The Wall Street Journal  
The #1-selling Outlook data conversion tool since 2002
Ready to run with every version of Microsoft® Outlook, O2M lets you choose which Outlook folders to export, and how. Export all of your email and calendar items, or perform incremental exports by telling O2M to only export recent items that fall within a date range you specify. Email attachments can be stripped from emails, saved inside emails, or even saved as detached, stand-alone files — a great way to move all your Outlook attachments to an archive folder quickly. Best of all, O2M supports industry-standard .mbox, vCard, and iCal file formats, so your exported Outlook data will be ready to import into third-party email, contact, and calendar programs that support these standards.

It's no wonder O2M has been the #1 bestselling Outlook converter since 2002, and a favorite tool used by Apple at its in-store Genius Bars around the world!
