Redknapp was moved to discredit a wave of speculation in which it was claimed he had quit with a year still to run on his Spurs contract.
Negotiations over a new deal have stalled since the start of the year when the 65-year-old was linked with the then vacant England manager's job.
In the past week Redknapp has made it known he would be uncomfortable heading into the new season without a longer deal while also defending his relationship with chairman Daniel Levy.
And the former Portsmouth boss was again forced on the back foot this evening as he denied more exit rumours, telling ESPN: "No, I haven't resigned, and I have no idea why it is being suggested that I have resigned.
"This is an outrage; an absolute liberty for people to be putting around this kind of rumour on the internet.
"It is not true, there is not a chance I will resign. Why should I?
"I have a year left on my contract."
Earlier this week Redknapp denied suggestions he was being courted by a club in Qatar after telling Tottenham to speed up negotiations to keep him at White hart Lane.
"The simple situation is, I've got a year left on my contract. It's up to Tottenham whether they want to extend that contract or not," he said.
"If they don't extend it and I go into my last year, it's not an easy one when players know you've only got a year left.
"It's not a case of me looking for security. What it's about is players knowing you've only got one year left on your contract and knowing that it doesn't work, basically.
"I think it's a situation of, 'well, he might not be here next year'.
"You don't let players run into the last year of their contract if you think they're any good, and you don't let managers run into the last year of their contract if you think they're any good.
"It's up to Tottenham. If they think I'm okay and I've done a decent job and deserve an extension, they'll give it to me.
"If Daniel doesn't think I'm worth it, that's up to him, that's up to the club. There's nothing I can do about it."
