Exchange Hosting with Unlimited Storage by IT Solutions Now

BTW, I would stay far, far away from 4smartphone. I used them for two years and always paid for my service upfront for a full year as they recommended and preferred. Midway through my contract (that I had paid for upfront), they switched from Exchange 2003 to Exchange 2007 and forced all their customers to upgrade. I didn't mind that but in addition to the forced upgrade, they increased their rates by about 50% and required me to pay the difference in the increased rates for the months remaining on my contract despite having already paid for the service upfront for the entire year. I told them I was willing to pay the higher rate once my contract was over with but I expected them to honor our current contract on the terms we had already agreed upon. They responded by sending me an email saying they were terminating my account and 10 minutes after the email arrived in my inbox, my account was gone (and they charged me a $15 cancellation fee on top of that!). Its a good thing I had backed up all my stuff beforehand! They did this to a number of their other customers as well who complained and this is why I will never do business with them.

The link I provided above is to the current hosted Exchange company I use (IT Solutions Now). Unlike 4 smartphone, they offer an unlimited sized mailbox for less than 4smartphone and have 24/7 free phone and email support. I have never experienced an outage with them as opposed to the multiple outages I had with 4smartphone. Highly recommend them. I don't want to hijack this thread any further so if you have questions about them or 4smartphone, feel free to PM me.
