I haven’t tried this yet, but I’m a big fan of Fookes’ other programs but this sounds like a great tool if you’re using one email client and you want to move on but can’t export easily: Aid4Mail – Convert, Export, Migrate, and Archive all your Email
Aid4Mail is a user-friendly Windows tool that helps you migrate your email messages to a different mail client, export them for viewing through Internet Explorer, MS Excel, or a database, convert them to extract or re-insert attachments, and archive them to save space or for compliance with legal requirements. It supports most popular mail client programs and processes all messages without losing any information, including those with file attachments and embedded contents like pictures and background images. Unlike other migration methods, Aid4Mail can also export message status information such as “unread”, “read”, “replied”, and “forwarded”. Aid4Mail produces results quickly and with great accuracy.
I’m going to give it a shot and I’ll let you know how it works out. Anyone come across some other solutions?
