Can not download emails to Thunderbird and addressbook vanished
A few days ago Thunderbird 24.6 stopped downloading emails from my att.net address, to my PC using Windows 8. All emails in my att.net inbox vanished. When I try to "check mail" to download emails I get this message "The DELE command did not succeed. Error marking a message as deleted. Mail server pop.att.yahoo.com responded: inactivity timeout".
I can access my emails on the yahoo/att webmail site.
My internet provider is Optimum. I can download messages from their email.
My personal Addressbook has also vanished from Thunderbird.
