After receiving the official OTA 2.2 update, my yahoo mail doesn't work. I got the low space warning three days after the update, so I deleted the HTC Mail accounts to start over since it had gotten to over 100MB. It loaded my msn just fine, but said that it couldn't authenticate my yahoo. I thought my PW was wrong, so I used the laptop to get a new PW, and confirmed it by logging into it on the laptop and again at work on the desktop. I went to add the new yahoo mail account to the phone, and I'm still getting the authentification failure message. Can someone please help! Yes, I still use yahoo for less important mail/notifications. LOL
