So right now I have 85-125 users on exchange 2003 sp2. Everything has been good for the last 5 years. I'm to the point I need to update our email system and I'm debating moving to a hosted solution, either exchange online or gmail. I was just wondering if anyone here has had any experience with either of these. I was sold on gmail at first but it appears it may be limited in some aspects such as handhelds. Plus my users are familiar with outlook. Any thoughts?
