EagleFiler-Archive Old Email-POP3

Good Day. Does anyone know if EagleFiler will work in my envionment:

Outlook 2011
pop3 account
OS 10.5

Have a huge Sent Items folder and would like to archive emails based on date. Will EagleFiler move items out of my Sent Items folder, but give me the ability to search them if necessary. Do I need to upgrade to 10.6?

Thanks

EagleFiler works with Outlook 2011 on both 10.5 and 10.6. When you import the messages, EagleFiler will copy them into its library where you can view and search them. Then you can delete the originals in Outlook.
