My AWS workmail domain is something like this:
mydomain-com.awsapps.com
I created a user, but when I try to log in from a browser, I get the following error. I am able to get the emails on my iPhone though.
Access Error This application has not been enabled for your directory. Please contact your Administrator for more details.
My problem is I was using the wrong URL, should be: https://mydomain-com.awsapps.com/mail
