I have a friend who runs a small business with 10-15 employees. He wants to be able to offer the following for his company: - Mail - Group calendar - File server - Print I'm not really in the field of small business solutions so I'm here to get some feedback. Are there any recommended "all in one" server appliances that can offer the above (the server would be hosted in the office and then require a SOHO Firewall and allow VPN tunneling/reverse proxy for remote users). The other option is online web office services (ie: Microsoft Office Live, etc). Cost is a concern, of course, but a good solution is required. Appreciate any feedback/advice.
