After updating passwords, I can no longer send eMails via Outlook

This morning I logged into xfinity.com and was asked to update my password. I have 4 eMail accounts across 2 different desktops for different family members. I changed the password on two of my accounts. I then went into Outlook and updated the password for those 2 accounts. Right after doing that, I was no longer able to send eMails via Outlook. I was able to receive eMails.. This happened on all 4 accounts at the same time even though I only changed password on 2 of them. I then logged back into Xfinity.com and was able to both send and receive emails. It only stopped working on Outlook.

Here are the error messages that I received when trying to send an eMail.

Sending reported error (0x800CCC67). ESMTP server temporarily not available, please contact support.

I spoke to someone at Xfinity this morning and they claim there is no issue on their part.

I have tried everything that I could find info on. I turned off the firewall, anti virus pgms, etc. But still have this issue.

I also physically deleted one of the eMail accounts and added it back in. Still cannot send eMails via Outlook.

Very frustrating spending all day trying different things only to end up failing. Searchin the Internet I have seen others who have posted same issue after updating their passwords. They too have not received an answer on how to fix the issue.

I had a somewhat similar situation and I found a solution that worked for me:

1. sign in to your xfinity connect email account

2. Go to settings (cog wheel on top right) and click on: Email Settings

3. Click Security

4. Click the square that says: Third Party Security Setting.

Done.

Repeat for each email account.

@user_SAS - Oh no! Have you tried resetting the password on the Outlook email client you use on your mobile phone?

I'm using Outlook 365 on Windows 11. I have had intermittent, mostly no connection Pop Up box which asks for server user name and password for three months now.

Today I deleted the comcast account from Outlook. I logged into xfinity on the web to a) check the password I reset a few weeks ago works and b) verify the allow third-party email connections was still checked under gear settings, security. I closed Outlook and deleted all the roaming cache files (C:\Users\ME\AppData\Local\Microsoft\Outlook\RoamCache). I restarted the Outlook 365 app and tried to add back the xfinity email account as IMAP. I immediately got the recurring popup box and couldn't proceed further. Nice.....(not). Made sure the "new" xfinity" email account was deleted in Outlook and closed outlook again, verifying in Task manager that it was completely shut down. Deleted roaming cache again

REBOOTED ROUTER.

REBOOTED COMPUTER

No VPN (not that I think that is making any difference nor had it at any time, IMHO)

Opened Outlook, created new xfinity account. that my setting is SSL/TLS and not just plain SSL as indicated in all of Comcasts "helpful" guides.

Double checked IMAP ports. Note that Outlook 365 allows SSL/TLS and not just plain SSL as indicated in all of Comcasts "helpful" guides.

It worked (for now????)
