This option basically involves the outsourcing of your email in its entirety. The outsourcing company will manage every aspect of your email services including security, spam protection and backup systems. The company takes care of everything that an in-house administrator would have done.
You should be able to feel at ease knowing that this company is taking care of all of your email infrastructure needs. They’ll store all of your email as it is received; it will be removed from the server when it is downloaded by the user. This helps to prevent those pesky “lost” emails and unfiltered spam getting into your office. Plus, it saves you a lot of money as you don’t have to use valuable resources for storing emails and having your own bandwidth. Everything is taken care of at the outsourcing company’s offices. Everything is stored on their servers. Your only encounter with the email functions would be when you add a new user to the network or send and receive email yourself. All security issues are taken care of on the outsourced server as well, so you don’t have to worry about updating individual software on each computer—though you should do that anyway—for email security purposes.
