Ulster were left gutted after Duncan Weir's 82nd minute drop goal secured Edinburgh a 17-16 win over Ulster in Belfast.
The win propelled the Scots above Ulster into third place in the Conference B standings of the Guinness PRO14.
Tries from winger Jason Harries and lock Lewis Carmichael along with two conversions from Sam Hidalgo-Clyne, along with Weir's drop goal, earned the Scots the four points.
All Ulster's points came from John Cooney.
Ulster head coach Jono Gibbes had no excuses.
