I'm new to sharepoint and am looking at using sharepoint in a project
where users need to share documents as well as certain project related
emails. The thought is that users can drag emails from outlook into a
certain 'workspace' for s specific sharepoint site they are associated
with. These mails will then be accessible for all users that have
access to that workspace.

My question is whether there is any way to do this via sharepoint /
outlook or if there are any best practices to deal with such a problem.
