Can't send email from outlook
Starting a couple days ago, Outlook stopped sending emails for my comcast.net account. I can still receive emails. I can also ping the port at smtp.comcast.net:465. It seems my attempt to connect to the port is being rejected by the server. Password is correct (am receiving emails).

Was experiencing this sending issue as well. I was always able to receive in Outlook (windows PC), but not send. Would receive the error messages that others have shared above (also see my screenshot below from the Outlook error). When trying to update the outgoing port value in Outlook configurations, the change couldn't complete as it couldn't establish a secure connection.
I could both send and receive through Xfinity.com's web mail as well as my email client on iPhone. Trying all the different work arounds and different ports mentioned above and in articles linked above didn't solve the issue, but I was able to find a solution that allowed sending to start working from Outlook on my PC.
I run Norton on my PC and the Norton VPN was set to auto-start and was running. I tried turning off the VPN and then Outlook was able to complete the configuration and send email. So, Xfinity is not liking something related to when the VPN is up and running. VPN location is set to Auto, so not sure where Norton was connecting to, or if Xfinity isn't allowing the connection because something is hidden by the VPN tunnel that it wants to see/inspect or know before allowing the connection, but that was my solve.

no issues receiving emails on 365 but cannot send. Just sits in drafts. Have had to use another outlook email address to send anything.
Do we have a fix?
Thanks

Outgoing smtp.comcast (port 465) and incoming imap.comcast.net (port 993).

Started this morning (6-10-24) cannot receive or send emails from my comcast account either through Outlook or my Iphone. Seems like a server issue that I have experienced before. Incoming is imap.comcast.net (port 465) and outgoing smtp.comcast.net (port 993). Spoke with CR rep who had a te3chnician call me back, unable to resolve issue, told he will call back in 2 hours, its been 4 + hours and still unable to use my email.

06/17/2024. Same issues 8 am to 8 pm can not send or receive.Started when I install frontier service with eero modem/router fiber optic. Outlook on pc, iPad or iPhone same issue. Avoid the eero connection no issue All other service and devices work fine on the eero device. Tried adding to list of valid sites on the eero device no luck Sending using gmail works fine. If there is nothing in my outbox being sent send/receive cycles with no error. Very frustrating. Others still having this problem? Is is only eero modem or are there others having this issueo

I am having the same issue where Outlook says it can't login to the SMTP server. I can get email.
I did have to login to the comcast email and I found that they wanted me to change my password. Which I have done and I have updated it in Outlook.
I am still getting the same problem where it pop ups as if I have the wrong password BUT if I click OK to it the same pop up comes up again and if I click OK on that, THEN it sends my email.
I have tried changing from port 465 to 587 but it won't save the changes because the error of logging in on one try.
additionally i can't send email from my iphone.

Have this same issue starting a few weeks ago, I have 2 Comcast accounts on Outlook, 1 will work fine, the other will not send, and then randomly they both work and then randomly the other account that was not working gets the issue and the other one becomes fine.
If I switch to the "New Outlook" it seems to work fine, not sure if all this started the first time I tried the "New Outlook" but timing seems about then. I've looked at all the suggested possible issues but no solution.
The "New Outlook" does not have the same functionality as the desktop so don't want to use that.
For myself, I do think this might be a Microsoft issue as I have non-Comcast accounts that also have issues sending email thru Outlook. I rarely use those but testing them today they would not send. They worked fine in the "New Outlook"

I have a similar intermittent issue. But when it happens, I keep getting the box to put my password in (already filled in correctly), and it just keeps popping up. Annoying. I also keep getting the non-encrypted connection to the Xfinity server where I get email but can't send emails from Outlook. Really pisses me off! I have to 'draft' my email in outlook 365 (since I get a send error), and then move it from my outbox to draft folder. Then use my trusty Apply phone and send the email from my draft emails.
What I'm forced to do many times is to delete my email from outlook 365, wait a day or so and re-add again to outlook 365. So annoying!!!!!!!!!!!!!!!!

I am having trouble sending my comcast.net emails thru MSN365 new version. Sits in drafts for a long time. If I have any attachment, it doesn't seem to go thru anymore.

I am unable to send emails from my outlook. I can receive but not send. I have imap and have used the 465 and the 587 ports. I use Spectrum, it is my only option here. Can you help me fix this?

My outlook email just stopped sending emails for COMCAST. Xfinity did want a password change which I did. It does receive emails after the password change. And I can send and receive emails on my iPhone after the password change. I have seen this problem with a number of customers on several threads. I have checked several places in outlook to change the updated password and SMTP settings. Some users experience intermittent issues. I am hoping that is what it is for me. I also tried rebooting laptop and router.

Changing the port to 465 for incoming mail in Outlook has seemed to resolve my issue.

I am also having this problem. When Outlook tries to send a test email I get a message that the server rejected my login. I can login to my xfinity email online just fine.

Same thing happening to me and my wife. Can send emails but outgoing server is refusing the connection. Occurs on both PC and iPhone. Outlook on the PC's and mail on the phones. Have tried all of the suggestion provided in these threads. No luck. This is obviously an xfinity issue and is in short a failure of service that is being paid for by customers. Lets see what the BBB or an attorney has to say about it. Maybe then xfinity will consider correcting their issue.
