A bumper crowd at the Store First Stadium failed to inspire struggling Stanley to their first League Two win of the season.
The Reds ended an eight-game losing streak with a draw at Plymouth last week but they failed to follow that up at home on Friday night.
Zavon Hines broke the deadlock in the 56th minute for mid-table Dagenham & Redbridge and Rhys Murphy doubled their lead five minutes later.
Substitute James Gray pulled one back in the 90th minute but it wasn't enough to stop the rock-bottom Reds avoiding an eighth defeat in 10 league games.
The match was brought forward with the hope of attracting a bigger crowd and the 'Fans' Friday' promotion did the trick, with 600 more fans in the home end compared to their last match here.
Yet they saw Dagenham have the better of a tight first half, with Hines denied by Marcus Bettinelli early in while Murphy had a shot blocked from a corner.
Stanley replied with Peter Murphy heading against a post from a Lee Naylor corner a loose touch by visiting keeper Chris Lewington almost handed Kayode Odejayi an open goal.
And just before the break, Bettinelli made another decent save to deny Murphy from a Hines free-kick.
Stanley made a positive start to the second half and Shay McCartan missed a great chance as he somehow headed wide from Tom Aldred's knock-down following a Naylor corner.
And Dagenham showed him how it's done moments later as they broke from an Accy throw, Murphy split the Reds' defence and Hines coolly converted to open the scoring.
Stanley then brought on winger James Caton, their new loan signing from Blackpool, but the Daggers broke again after Accy lost the ball down the right and Hines returned the favour for Murphy, who slotted home with ease.
Manager James Beattie named himself on the bench for the first time this season but chose not to come on as Hines and Daggers' sub Chris Dickson went close.
Gray then turned in the rebound after Will Hatfield's shot was saved but it was too late for Stanley to mount a fightback.
