Thunderbird recently upgraded (?) to Version 15 on my Windows 10 laptop. Since them, when I go to look at the "Trash" folder, I get the message: "Unable to open the summary file for Trash on username@gmail.com. Perhaps there was an error on disk, or the full path is too long." I was able to fix it temporarily by restarting Windows 10, but the error is back a few hours later.

I use both Thunderbird and Outlook for my cox.net email account. I can receive incoming emails using Thunderbird but cannot send emails, and I can both receive and send emails using Outlook. The server settings are identical for both Thunderbird and Outlook - imap with STARTTLS and port 993 and smtp with STARTTLS and port 587. When Thunderbird is unable to send an email, I get a balloon that indicates that the smtp server cannot recognize my email address, which is [email removed]@cox.net.
