Using Work Adobe account - work email didn't allow me to sign in

My employer has a licence/account with adobe. I've always been able to use it no issues. However, after a recent software update, I have been unable to use Adobe Acrobat, When opening it asks for my sign in but won't recognise my email or direct me as per policy to sign in through my employee account. I attempted to create the account with my work email, thinking that would re-direct me to sign in with my work credentials instead it auto created a personal account. I need to cancel/delete that personal account completely.
