This is driving me nuts. All of a sudden, my email app on my phone failed to connect. It required me to go thru a password reset process on XFINITY. I did that. (I verified by logging into their web client). I updated my Settings for IMAP & SMTP in the Outlook 2021 client. I am again receiving emails, but every time I try to SEND, I get a popup telling me the SMTP.COMCAST.NET server does not recognize my user/pass combo. I have entered it correctly, multiple times. It just refuses to accept it. So I can't SEND emails on either my PC Client (or my phone app).

Anyone encounter this? What's the solution? TIA
 
Open control panel > Mail and edit the profile there- double click on the comcast account and update the password at the bottom of the screen then click More Settings and verify the setting is to use the same as incoming. Then test it.

The other option is to delete the account and add it back - but if you do that, if you have calendar and contacts in folder named “(This computer only)", export those folders first. (Or tasks, notes.)

Thanks ... I got to that also via the OUTLOOK SETTINGS / SERVER selection. Every time I selected the 2nd half of the screen (SMTP related), I would select "use same settings ..." and it continued to fail. I tried it like 15-20 times. So I finally gave up and tried again the next morning. It suddenly was working... So No idea what was going on. I can only blame it on XFINITY side. All working now. Thanks.
