I work for a company that has about 30 emails, plus 5 on another domain. They also want an entirely separate company with 5 emails to coexist with the other 2 (35 total but 2 domains) emails (they're for the same company and will have shared contacts/ public folders). One needs to be on it's own account, it's owned by a partner but is totally his own company. I'm currently using Rackspace for the email but it's $3 more per user for exchange, so it's about $105 month more for exchange services. Should I/can I set it up on server 2008R2 more cheaply, and also maintain it? The last time I set it up was on on 2003, so I'm pretty much a newbie. Any and all suggestions are appreciated!!!!
