I haven't seen replies I posted long ago showing so I am not sure if they posted or anyone saw them so I thought I would try again. Are you saying due to IE 11 no longer being supported QB2018 is no longer usable? What if installed on computer with IE 11 and no microsoft edge?

I have tried several suggestions and am now having a problem that passwords saying not correct. I have succeeded resetitng 1 but get various errors with the other 2 and cannot reset them
