Ah okay that's a solution that was not available when I tried the home user package. I was told it was not possible to use an actual domain like you can on the business package. I ran the small business package for 6 months but they wanted £12 a month for it and the office apps as we all know are available for Mac anyway free, and all smartphones and tablets.
Google for work is £6.60 a month and I think still offers the better service. It was not complicated to set it up on MS but it was a dream on Google, mainly because TSOhost have a "1 click and you are set up on google" button
