Xfinity Connect email error: "...provided login data to access mail server imap.comcast.net seem to be wrong..."

I periodically get the pop-up error message on my Xfinity Connect browser-based email client (Window 10 Home, and Android), "Error The provided login data to access mail server imap.comcast.net seem to be wrong. Please correct them." The problem is consistent across types of devices and various browsers.

I have gotten this error message for years, and I just dismiss it. A half-hour later, it pops up again. It would be nice, though, to actually fix the problem, if that is not too time-consuming. I will not call support on the phone because they have time-consuming protocols for the user to go through before they start to investigate the problem.

Do you have any suggestions?

... The provided login data to access mail server imap.comcast.net seem to be wrong. Please correct them ...

That happens when you have added an external/secondary email address to https://connect.xfinity.com/, and the password for the secondary account changes.

To fix the problem, first verify that you can log into the account for the secondary address. If that's working properly you'll need to change the password stored in the webmail settings for the account showing the error message. Click (gear icon) / Email Settings / Accounts and then Edit for the account with the changed password. Enter the current password for that address under "Incoming server / Password", then click "Save".

Your access to your secondary account should be restored. Please let me know if this helps!

@XfinityDilary Are you still available to respond regarding this issue. It just happened to me yesterday and now I can't access either of my secondary email accounts. All of the settings are correct and the PW has not changed for months. I can't bypass the error message so I can't login. I have access to my primary comcast email account, but all my important info is under my secondary email accounts. Please help. Thank you in advance. This is so frustrating. Of course when I try to call for support I get stuck in a vicious cycle of useless auto-responses and options.

After many years of using the web-based email for the primary and secondary emails I received these error messages for the secondary email:

"Error
The provided login data to access mail server imap.comcast.net seem to be wrong. Please correct them."

"The entered credential or authentication information does not work or are no longer accepted by provider. Please change them"

Nothing was changed. I did try and verify the settings and did change the password but that did not resolve the issue.

PLEASE ASSIST

Hi there, thanks so much for reaching out — and I can absolutely see how frustrating this must be, especially when everything was working just fine before. I've definitely been in that spot myself where it feels like something changed out of nowhere, so you're not alone!

Based on the error messages you're seeing, it sounds like your secondary email may be running into a known update with security settings. Even if nothing was changed manually on your side, sometimes providers (like Comcast or your email app) update security standards behind the scenes, which can cause connection issues with IMAP servers.

Here’s what we recommend trying next:

First, make sure you are using the correct server settings:

Incoming Mail Server (IMAP): imap.comcast.net — Port 993 with SSL/TLS
Outgoing Mail Server (SMTP): smtp.comcast.net — Port 587 with SSL/TLS
Username: Your full Comcast email address
Password: Your updated/current password

If everything looks good there and you’re still getting the error, let us know and we will be happy to assist you further!
