We are in the planning stages of moving from our current email platform to Exchange 2010. Currently our users are able to share folders where they can store project emails/information regarding the project that they recieve from both internal and external sources (they only share internally however). We've seen that Exchange 2010 does support public folders which seems to be about what we're doing, but also we've seen that it isn't recommended and it's days seem to be numbered.
Our users are (understandably) a bit concerned over our determination to NOT user public folders in 2010, as this is functionality that is quite handy for a number of people.
We've seen lots of suggestions for SharePoint, however that isn't in the cards for at least another fiscal year, we've suggested just saving the information out to a shared location on the file server, but that doesn't have the convenience of all the folders in one location and allowing the end user to determine who has rights to view the files.
Does anyone have any suggestions for how they would handle providing a sharing mechanism without utilizing public folders?
