Outlook & SharePoint – Simple email archival

We are in the need of some general email management for a group of project / power users.  The need is fairly simple, to copy / move an email from MS Outlook directly in to SharePoint.  Having a prompt to ask for some metadata would be a nice, but not necessary bonus.

I know of some 3rd party apps, KnowledgeLake / Calligo as examples.  If possible, we would like to avoid them, or at least, find one which is super simple for our users.  We don’t want / need additional features.

Any feedback would be welcome,
