IMAP Settings Not Working

I use "Betterbird" which is a clone of "Thunderbird" on my Linux workstation.  I have tried to set up my comcast IMAP account many times but it always fails.  I can set up the POP account OK.  My IMAP settings work on the web version of Xfinity eMail.  I have attempted to use every possible setting listed on the various help pages for connecting the IMAP account but it always fails with a "cannot connect" separate message window.  I am wondering if there is a glitch somewhere.  I have switched back to "Thunderbird" an attempted the same procedure and settings, but still receive the failure message.   I am out of ideas.  I would appreciate some advice.  Meanwhile I continue to use the Xfinity eMail web site.  BTW:  My IMAP settings work on both my Android phone and on my iPad devices -- all settings are the same as those put forth on the eMail connection settings pages.

Regards to the Group,

Just to be thorough, you have taken these steps, correct?

To set up IMAP for Xfinity Email, use the following settings:

**Incoming Server:**
- IMAP server: imap.comcast.net
- Security type: SSL
- Port: 993
- Username: Your Comcast email address
- Password: Your email password

**Outgoing Server:**
- SMTP server: smtp.comcast.net
- Security type: SSL
- Port: 465
- Username: Your Comcast email address
- Password: Your email password

Ensure to select the options to sync email and notify when email arrives during setup. For more details, refer to the specific setup guides for your device.

I re-installed my Comcast email using the settings shown above.  There is no place to enter my account password but i used the email program "password storage" to duble check that my passwords as entered were correct.  They are.  Again, I received the same message in a text box that "settings are invalid".

Still using the web email access.  This may be a problem with the Betterbird application which replaced Thunderbird.  My next step is to delete and purge Betterbird and reinstall a fresh iteration of Thunderbird.

Thanks for the advice.

I'm sad to hear that didn't work. We may need to submit a ticket for this. 

Please send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you. 

 

How to Send Us a Direct Message:

Click "Sign In" if necessary.
Click the "Direct Messaging" icon or visit Xfinity Direct Messaging.
Click the "New message" (pencil and paper) icon.
In the "To:" line, type "Xfinity Support".
As you type, a drop-down list will appear. Select "Xfinity Support" from that list.
A "Xfinity Support" graphic will replace the "To:" line.
Type your message in the text area near the bottom of the window.
Press Enter to send it.
