- 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. Guest • Jul 2017 • 1 agrees and 0 disagrees

- The total lack of security, besided the https login page, there exists none within their service. NO end to end / yahoo to yahoo, based security what-so-ever. Besides more than likely owned by Google, which is snoopers lap dog, and a data-mining company, Yahoo will lock a user out of their free account, without notice. Besides Yahoo over-inflates the storage amounts in a free accounts. Guest • Jul 2017 • 2 agrees and 0 disagrees
