When it comes to email, Google apps has been a Godsend. It enables small companies to run efficient cloud based email systems that are protected and secure. This service is provided by Google for free for up to 10 users, allowing small companies to avoid the high cost of an exchange server entirely. Unfortunately, free is not always free, since a service like this does not come with any technical support. That is where we come in. We recently had a client with an issue with their Google apps account. The account worked fine, but when someone with an MSN, Live, or Hotmail email address would try to contact them, they would get an undeliverable error, its available after the break.
