I can send emails and do receive them on my iphone but when I try to receive them on my windows laptop I get a message box stating, "Sending of password for user g*** did not succeed. Mail server pop.optonline.net responded: Service Temporarily Unavailable". This happened after the latest windows update. I also noticed in windows settings that there are two optonline accounts now. Just for kicks I opened windows mail and there were the past couple of days of inbox activity. Did windows block my Thunderbird account? How do I get it back? Thanks for any help offered.
