Aston Villa manager Lambert famously guided the Canaries into the Premier League from League One with successive promotions, and then kept them up.
But the Scot quit as boss in June 2012 in a furious row over broken contractual promises.
Lambert feels he had an unequivocal clause in his deal giving him the right to leave for a specific fee.
But when Villa came calling after sacking Alex McLeish, Norwich quoted them a much higher figure.
It saw Lambert resign and sue for constructive dismissal - with the LMA’s backing - in a bitter compensation wrangle which went to tribunal.
The dispute was finally resolved last Christmas when the Villans paid the original compensation fee and Norwich paid a with-held bonus.
But Lambert still refuses to speak to his nemesis David McNally, the Norwich chief executive, and the Norfolk club's chairman, Alan Bowkett.
He says he is “fine” with City’s co-owner the celebrity chef Delia Smith, but will boycott the boardroom and handshakes this weekend as Villa visit East Anglia.
Lambert insisted: “There will be none of that - oh God no. It will never heal, that.
“I know what happened. It was nothing that was on the pitch. I’ve got to let it go now. It is history.
“I have nothing but good memories, but what went and happened after that happened.”
Lambert again left carrow Road all smiles though after a winner on 30 minutes from Libor Kozak's
In an exciting game, an Andreas Weimann shot for Villa hit the post and Norwich's Robert Snodgrass had a penalty saved by Brad Guzan after Ciaran Clark handled.
Gary Hooper came off the bench for his Norwich debut late on and had an effort tipped over by Guzan.
The Canaries have only lost two of their last 12 league games at Carrow Road - both to Villa.
