Outlook quit working with comcast email

I found this from a web search, hope it helps.

For me, this problem started maybe 6 months ago. Not only asking repeatedly for the passwords, but also synchronization issues and other kinds of random connection errors. I have spent months trying to just live with Outlook365 repeatedly popping up prompting me for the passwords for the two Comcast Email accounts even though they are right there and 'save to password list' is checked. Cancelling pop up or just closing it did not matter - came right back up. Off and on I tried various solutions, I found on the Web, but nothing worked and I have had to close my Outlook program to stop the incessant pop-ups. Yesterday and today, something I did has worked for me (fingers crossed, though). I don't know if it will help others.

First, I run Windows 11 on an HP PC, with everything updated and optimized. No viruses. In Outlook, I have my Microsoft Exchange email account (@.edu) and two Comcast email accounts (@comcast.net). I also just added a Gmail email account. I did the necessary "allow 3rd party programs" in my Comcast account settings months ago when this all first started. I also have Norton 360 and Norton Utilities. My Norton VPN is on. I have an annual subscription to Microsoft365.

Last night, I did this because I was so frustrated. I removed the two Comcast email accounts completely from Outlook, leaving only my Exchange. I then went into my on-line Comcast account and changed their passwords (just to have something new). Closed Outlook. I then double-checked my PC to make sure everything was up-to-date and ran both my Norton360 program (for viruses) and the Norton Utilities program (it does a PC, Windows, and Internet Cleanup). I shut down the PC for the night.

Today, I just started from scratch. After booting up my PC, I proceeded to configure Microsoft Outlook365 as follows:

1. Open Outlook.
2. Click the File menu.
3. Click Add Account.
4. Enter your Comcast.net email address (e.g., ******@comcast.net).
5. Enter your Comcast.net password, then click Connect.
6. Click Done when your account was successfully added.
7. You should see something like this:
   

Next, I followed these instructions:

1. Open Outlook.
2. Click the File menu.
3. Click the Account Settings button, but if you have more than one email account like I do, make sure in the Account Information at the top of the display it shows your specific Comcast account. If not, choose the down arrow and pick it before going on to step 4. Looks like this:

4. Click on the Server Settings.
5. Click Outgoing mail.
6. Change the port to 465 Or 587 (I used 465)
7. Make sure SSL/TLS is selected, next to Encryption method.
8. Click Next to save your settings.

Will this work for you? Don't know...but, maybe it will help someone. I have my Outlook program loaded, have been working on my PC for an hour or so, not one pop-up or synchronization issue. Fingers crossed it will stay this way. Good luck all.

This is not working for me. So frustrated.

Hello, I would recommend double checking your password and try generating a new app password.

To create a new password for Comcast: (Setup "Comcast Email IMAP Settings" to configure account in other Clients (bitrecover.com))
You need to disable 2 Factor authentication in your Comcast email account. If it is enable you can generate an app password and use the same app password to Login into the Software.

1. Download the Xfinity Authenticator app
2. Open the app and select Register with Xfinity.
3. Use your Xfinity ID and password to sign in.
4. Enter Code
5. After the Verification>> On Two Step Verification.
6. Create App Password.

Use this new password when you are in your account settings on Outlook and replace the old password with the new app password.

Thank you and please keep me updated
