Security Certificate that cannot be verified

I have multiple "comcast" email addresses that I use through Outlook, Microsoft 365. On one email I constantly get this warning, none of my other comcast emails do this. I click yes and it gets my email but I want to get this taken care of so it doesn't come up. What is causing this to sporadically come up on this one email?

I have deleted the email and added it back in, POP3, and this makes no difference.

On my own investigation to figure this out I found what was causing this issue in my account. When going from POP3 -> IMAP I had to delete the POP3 account and create an IMAP account. When doing this and it was completed I received this error message as noted above. When I went into the settings to make sure that ports, addresses and so forth were correct I noticed that there was a "." put in at the end of the inbound and outbound maps to server. Once the "." was taken out everything on all accounts was correct.

I already looked at the second link and the reference they posted was 2 years ago. The link in this "You should be able to use the following link https://comca.st/3IfzGMj to repair or add the email one more time." doesn't go anywhere, no good. I tried to correct the spelling of comcast in the link because of the period but it didn't help.

The first site is just information and doesn't tell me anything at all other than what is known. I have 3 other comcast emails in Microsoft 365 Outlook and they work without a problem.

Are there any other ways to check this and get this notice to stop?

@cpupro thank you for the follow up letting us know the link is no longer good, I attempted and get the same message that the link no longer exists. 

I had a quick question if you don't mind me asking, have you attempted to log in directly on our website to see if the error persists when not using the Outlook 3rd party client? 

 

This could help determine if it is an email issue, or the 3rd party client that could be causing the message to pop. I'm sure you have already checked the Outlook settings listed here to ensure they're set up correctly:https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email.

I don't have an issue when going to the website and logging in, terrible layout and then last thing that I will use.

Outlook from Microsoft 365 has worked perfectly for the 4 "comcast" email accounts that I have. It is only one of the emails that is giving me the trouble. ALL the emails are POP3 accounts, I want all my email in .pst files on my computer, not stored on comcast servers, don't trust them.

I will go back, delete the email that's a problem and go through this again.

I appreciate you attempting to delete and set up the email again following the link the article we gave you. Please let us know once that has been completed if you are still seeing the error message.

Still seeing the error message. I just compared 3 comcast emails. ALL set up identically, ALL allowing 3rd party apps to use and so forth. Only the one email is having this error come up, the other two have no issues.

I also made sure that I update Microsoft 365 Outlook and any other updates that needed to be done.

At this point it looks like I'm just going to have to click on this when it pops up and say I will use the server so it goes away.

Nothing that I can see to try anymore.

... "You should be able to use the following link https://comca.st/3IfzGMj ... I tried to correct the spelling of comcast in the link because of the period ...

"comca.st" is a pointer to link shortener Bitly. If you follow https://comca.st/3IfzGMj+ (note the + sign) you'll find that the link points to https://www.xfinity.com/support/articles/configure-outlook-365-email?linkId=153622150, which is no longer valid.

Many months ago Comcast/Xfinity made the bizarre decision to drop the pages with specific instructions for 3rd party email programs, devices, and apps, and replace them with links to generic instructions on respective third party sites. So now to setup outlook for use with Comcast.net email you have to follow the Outlook link on https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email, which leads to Microsoft's generic page at https://support.microsoft.com/en-us/office/add-an-email-account-to-outlook-for-windows-6e27792a-9267-4aa4-8bb6-c84ef146101b. Not nearly as helpful as the page which was removed.

Edit: plus sign note, fix typos

Still no change, will just have to live with the issue. Why I have 3 comcast emails that work correctly and 1 that does not. ALL are working together in the same Microsoft 365 Outlook is beyond me.

ALL the emails are identical as far as the settings information to receive/send comcast emails in POP3. They have been that way for years.

I have the exact same issue with my new Windows 11 PC. The same settings work fine on my older Windows 10 machines.
