accessing Mail with OS X El Capitan
I just installed OS X El Capitan this morning and can no longer access my MSN email via the mail app. I have an iMac (27" Mid 2011, 2.7 GHz Intel Core i5, 8 GB 1333 MHz DDR3 desktop. The Mail app says it can't connect to the account "MSN" and asks for my password. When I enter it, I get the message "Unable to verify account name or password." Yet, I can still go to Safari, then to Microsoft and enter my UserID and password, I can get my email that way. So, my password to the Mail app is correct. Any quick fixes?
