[AC Question]

I tried to use the default android mail app
i used the automatic setup to configure the account

What can i do?

I'm getting the same thing - "Cannot securely connect to server". I've had it setup for 2 years and noticed a couple of days ago that my folders would not sync. I tried removing the account and adding it again and get the above error message.

Welcome to Android Central. Have you tried logging in online to see if additional security has been put into place?

You're going to have to either go online to your yahoo account security settings, and turn on 'allow less secure connections' or the simpler method is to download the yahoo mail app on your phone. Yahoo changed their security protocols to not allow less secure connections by default. It starts affecting different folks at different times.
