First, all email clients need basic information to allow setup. Thunderbird is no more complicated than other email clients and easier than many. To set up an account, people need to know the name, port, and security requirements of the mail incoming server and the mail outgoing server. Your employer should provide you with that information. Once you have that and still need assistance, we will be glad to help.

How about step by step for setting up a new email account.

Every time I follow the printed direction the system wants to set up a new email account for me and will not except the new email account that I need to established. Never encountered this issue before, setting up a new email account was as easy as 1,2,3, and yes your system changes, removing 'Add New Account' from the list, has made it far more difficult.

I have never understood the need to change something that is working.

If you are just setting up Thunderbird, the first screen prompts for info on your email account. If TB is aware of the email host, such as Gmail, you need to key in very little, but there is a 'manual config' button if you want to fill in more info. If you are already using TB and want to add an account, Click File>New>Existing mail account.

That may not be exactly what you're asking, but it's a start. Please let me know what else will help you.

Every attempt ends up with a message -Configuration could not be verified - setting have been verified, yet Thunderbird will not setup account????

Could you do a screenshot of the email setup window at the time you get the message? Might it be that the password is incorrect?

Sorry I have search Thunderbird for the direction to take a 'Screen Shot' - Directions please

That is done by other software or the PrintScreen key. There is a free program that does that at bluefive dot pair dot com called snapshot.

Manual configuration Incoming server - Protocol: pop3 Hostname: mail.comcast.net Port: 995 Connection security: SSL/TLS Authentication method: Normal Password Username: membership@clancunninghamintl.org

Outgoing server Hostname: smtp.comcast.net Port: 465 Connection security: SSL/TLS Authentication method: Normal Password Username: membership@clancunninghamintl.org

Message: Configuration could not be verified. If your username and password are correct, it's likely the server Administrator has disabled the selected configuration for your account. Try selecting another protocol.

I have confirmed with Comcast that these settings are correct.

Well, if the settings are correct, the problem may be that your email id is not 'membership' or that the password you were given is not correct. Is it possible that Comcast requires a unique APP password? A quick web search indicates that comcast passwords are administered by Xfinity. I suggest you log into the web account to verify the password and user id. If that works, then a special APP password may be required for an email client.
