On my Laptop, I have four email boxes mileoak@rogers.com, i-75dave@rogers.com, dave_hunter@rogers.com & book-orders@rogers.com. Whenever I try to get messages, I get a Thunderbird comment, "Connection to server pop.mail.yahoo.com was reset." My connection in and out of my accounts worked perfectly on September 10th. When I signed in to Thunderbird on the morning of the 11th, I received the above message. Here are the settings for dave_hunter@rogers.com (the least important of my accounts). Incoming server: pop.mail.yahoo.com Username: Dave_Hunter@rogers.com Port: 995 Security: SSL/TLS Authentication: OAuth2 SMTP server: smtp.broadband.rogers.com Port: 465 Security: no authentication User Name: Dave_Hunter Nothing changed at my end between September 10 and 11th. Have also used these settings for year with no problems. I recently received a suggestion from sfhowes and tried the changes suggested with no success. I'm in the middle of a heavy email sales campaign and have tried to switch to the Yahoo email menus which I find very cumbersome compared to Thunderbird. All the files I need are on my suspended Thunderbird system. Can somebody please get me back on track so I can start using Thunderbird again? Thankful blessings to whoever can solve this connection problem. I would even pay for professional help if it was available. Dave
