Hosted Exchange

Hosted Exchange: Can it Work for You?

Decent overview of the technical issues involved, but it doesn't answer the question about cost/benefit. The prices I see for hosted Exchange eclipse the cost of clients having SBS 2003.

Most small companies need at least a file/print server and high speed internet. Adding SBS 2003 and Exchange is incremental. Maybe I'm just a geek, but most small business people don't want another multi-hundred dollar per month cost and then not even have mail archives locally. Mail is considered intellectual property by lots of companies and having a multi-gigabyte store on someone else's server would keep them awake at night.
