Right now a popular method of document management in our organization is for groups of users to be on an email list for a particular client. This group receives emails from outside clients containing docs and pdfs of large file sizes. Each user stores them in outlook (non exchange) for future reference or archival purposes. This method has gotten out of hand. The volume has ticked up and users that have been here for a long time have enormous .pst files, not to mention that we have duplicate files all over the place, that are only accessible by users whom the files were sent to in the first place. What are my options here, without ramping up a massive document management project?
