unable to verify account name or password
good day, trying to re-add Mail account but get continuously the above message. I have checked and confirmed passwords etc. and everything works on other apple products. all the suggestions I see relate to an existing mail account however i had removed my mail account with the idea to re-install it. But cannot.
I am convinced that it has something to do with keychain but I cannot solve this, after hours of trying everything I could find.
Appreciate any help folks.
