We are looking for an email archive solution that maintains the folder structure that users have set up in Outlook. Most of the archive tools we have seen do the archiving at the server end and so do not store this information. This means if you have set up folders as a sort of library you will find it difficult to retrieve emails from your archive.
I remember seeing some software which kept the folder structure and message headers but archived the body and attachments and replaced them with an html link. Does anyone know of something similar or better.
