For some reason, Yahoo.com does not allow you to connect to your email via a client such as Outlook without paying a yearly fee, but Yahoo.ca does. They’ve got no complaints from me.
In Outlook, use the following settings… under Account > Account Settings, click “New”
on the bottom right, click “more settings”.
click the “outgoing server” tab, and change these settings.
on the “advanced” tab, change the above settings, then keep clicking the “ok”‘s until your back in your inbox.
