I have been trying to get my Comcast email configured for days with no luck. When I try to log in using my Comcast password I get a screen that shows "Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server. Reference #18.321c2e17.1727662977.283cff2b https://errors.edgesuite.net/18.321c2e17.1727662977.283cff2b. I have allowed access to third party apps on my Comcast account and I am able to access my email on the Comcast website with no problem. I saw something about disabling IPV6 but it said to go to Preferences or Options in the Settings menu. My version of Thunderbird (latest) doesn't have these menu options. I have tried various IMAP and SMTP Port settings I found on the internet and nothing works.

What are the settings for Comcast email in Thunderbird?

I have had two Gmail accounts on Tbird for about a year with no problems. Now I get unpredictable or no results trying to send or receive messages from the newer account. A message mentioning unsuccessful server authentification is the most common. "we have sent your message but not mentioned it in the "sent" folder due to connectivity problems" also occurs. I have absolutely no problem on iOS mail or Tbird running on MacOS. To the extent that I can decipher the iOS settings, there is no difference.

I use SMTP settings

Description: smtp.office365.com Server Name: smtp.office365.com Port: 587 User Name: mypersonalaccout@hotmail.com Authentication method: OAuth2 Connection Security: STARTTLS

but TB is incapable of sending email. Either I got dialog https://software9119.technology/__other/tb/dialog.png or error https://software9119.technology/__other/tb/timed-out.png.

I tried cleaning cache and made some re+/search with no avail. There seems to exist some Authenticated SMTP but this is only available on Exchange 365 while this is my personal Outlook.com account.

Thunderbird keeps asking me for the password of an email account every time I restart it. The account was removed from Thunderbird several months ago. Even when the account is set up again, it asks for the password in a continuous loop. The email account itself cannot be deleted or the password changed as it is used by multiple parties.

I have tried sevaral things and it seriously is driving me crazy...
