This is email, but it is ANYTHING BUT OPEN, and is run by Micro$oft, a leading participant in the PRISM surveillance program. This is not a privacy-friendly service.

Zoho seem to have a more user friendly way to contact customer support for any problems. OMBx does not have any links in their email, nor can users do a 'search and find their support contact info. So I be moving to very Zoho soon.
