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

@user_0ozxjl​ This is from the O365 Webmail? or the Desktop Outlook?  There's no error given?

Starting this morning (6-10-24) I cannot send or receive emails on outlook or my Iphone.  Email works on web based comcast email only.  Password is correct .  Outgoing smtp.comcast (port 465) and incoming imap.comcast.net (port 993).  Spoke with Xfinity customer service and second level tech this morning who asked me to wait two hours and he will call be back, that was 4 hours ago.

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.

Just a suggestion - is there any other email client that may be trying to sign on using an old password? That was my problem - an email client that I hadn't used in years was mistakenly opened on a laptop. It that had an obsolete password, kept trying to sign on, failed, tried again and again, and eventually comcast.com "suspended" the account - except that the web email service still worked fine - but all the other clients on my phone, tablet, and main PC were unable to send messages - they just got stuck in the Outbox. After a few hours, comcast.net reset the suspension, and everything worked fine. 
I wish rather than just suspend the ability to send emails from clients in a situation like this, there woudl be a message generated stating that the email service was suspended due to too many failed signons.

user_pa2ph7 We were seeing this concern with many Comcast customers on Monday. Are you still having email syncing issues in Outlook?

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.

@annej_ca​ It looks like your password has changed, however you didn't change your SMTP settings in your Outlook.  Please double check both your Incoming and Outgoing configuration.  If you're certain they're correct, we'll take another look.

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"

Hey there, KCSVEN, thanks for reaching out through Xfinity Forums regarding your Outlook issues. We definitely want to ensure that your email is working. Have you been in contact with Microsoft regarding the issue to see if they can help with any troubleshooting? Also, what troubleshooting steps have you tried already to resolve the issue?

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!!!!!!!!!!!!!!!!

Hello, @user_d196f7

Have you checked the settings in Outlook for incoming and outgoing emails? The account may be compromised along with not having a backup email or phone number on file. You may need to contact our Security Assurance team https://internet-security-site-web.ho-g3.cf.comcast.net/help/report-abuse to get this cleared up.

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.

user_0ozxjl Good morning, and thanks for reaching out with your mail issue with sending mail. We would be happy to help in any way we can to get this resolved for you. 

Can you send us a direct message with your full name, name of account holder (if different), and service address please?

To send a "Direct Message" to Xfinity Support:

Click "Sign In" if necessary

Click the "Direct Messaging" icon (speech bubble)

Click the "New message" (pencil and paper) icon

The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there

- As you are typing a drop-down list appears. Select "Xfinity Support" from that list

- An "Xfinity Support" graphic replaces the "To:" line

Type your message in the text area near the bottom of the window

Press Enter to send it

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?

I think the community will need some more information in order to help. One thing to confirm is that you do not have any other device - phone, laptop, PC, tablet - that may have an email client running that has an obsolete password and is trying to login in with that incorrect password. Comcast.net doesn't like email clients logging in repeatedly with a bad password and will suspend your ability to send emails for a period of time, and you get no notification of this action.

@user_xy48st​ It looks like your system is still using an incorrect password.  We can see authentication failures in the logs for your UID.  Please ensure you've updated the SMTP settings as well.  If you're still having an issue, please let us know.

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.

My outgoing server seems to already be 465, and it still doesn't work with VPN on sometimes. I guess it's like someone said, it's just some of the IPs that get banned not all of them.

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.

@user_tbospu​ Please ensure you change your password in both locations in Outlook. There is one for Inbound/Retreiving mail. and then another for SMTP/Outgoing.

HI Alex. I did exactly that with no change. I have even been on the phone with Xfinity tech support. Their workaround -- changing my passwords -- worked for like an hour. Any help?

user_412h8r Did you try changing the password first and then signing out and in again through the third-party email client?

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.

@ashelton​ I'm going to send you a DM.  As noted elsewhere, you likely need to change the password in more than one place.  But I'll try to send you some details about where this is happening.
