I am getting an error when trying to authenticate Exchange in my MacBook Pro in the Calendar app.
Everything works up to the point of authentication. If I authenticate with a wrong password it acknowledge the wrong password, so I am assuming that it passes the authentication step.
The error is: "The operation couldn't be completed. (com.apple.accounts error 3.)
I have deleted and references to Exchange and ADAL in keychain. And I already changed my password.
Despite this, I am able to sign up to the account for Apple Calendar app in my iPhone.
Any ideas on how to solve this?
