I am frustrated to the point of screaming!
My mother has been receiving this error for the past few days and I've gone through what I can think of in order to fix this.
I've deleted and re-setup her email account on Outlook 2016.
I've changed her email password.
I'm now unable to go into her account settings on Outlook 2016. I go into the Account Settings window and double click on her account. Instead of bringing up the regular interface to change servers, etc., it brings up the following:
I'll figure out a fix and it'll work for about 12 hours before the error message again comes up. Last night, I was even able to send from and receive to the account using her Outlook. This morning, nope.
I have been dealing with this daily for a week now and am tired of it. Help is needed! Thanks.
