One thing I do want to say. Microsoft really ramped up tech support. I was able to get through each time. Patrick spent an hour with me troubleshooting. I've spoke to several techs and they were very knowledgeable.
Also, there is an upgrade apps option on the Surface. The mail app keeps getting revised, so Microsoft engineers are obviously hard at work fixing bugs.
Having said all that, I'm returning Surface (so I won't be able to check to see if SBS (Small Business Server) settings were the problem. I am going to wait for a full version of Windows 8 so I can install other Windows 7 apps. I'll also wait until most of bugs seem to be worked out.
I think the Surface and WIndows 8 are potentially a strong products, and look forward to full implementation.
