I have about 30 users on a domain all using outlook 2003 running Windows XP Pro with an exchange server 2000. I know that the maximum size for a pst is 2GB, and I always try and keep them to a max of about 1.5GB. The problem is that some users have been here for years and now have 3 or 4 pst files each. These are storred on the server for backup purposes. This obviously uses quite a lot of bandwidth. I wonder if anybody knows or can suggest any methods to assist in this scenario to help reduce the traffic and/or pst usages.
