Can't send email from outlook

@user_05vioo​ Please send me a DM with the comcast.net username you're using when trying to send email.  We'll take a look at the logs.

@Zeek69​ Did you change your password in both places?  Incoming and Outgoing?

There is only one place to update the password in outlook.

I have been using it for my email for at least 15 years....I am with you.  Not happy with their customer service .... you can't just call and talk to someone on the phone to help with problems!  Very frustrating.  Hoping I can find a resolution for this though, as I am not ready to give up this email address yet.  I have a Spectrum router and modem.

Hello paivano are the emails in the Outbox attempting to send, and what is the error message you see in the headers when this fails?

The 4th person I talked to yesterday told me something I hadn't heard before:  that when you have linked email accounts, if each person updates their PW from xfinity website, then it can take many hours for the password change to take effect throughout the system.  However, if the user that controls all the linked email accounts changes it, it happens immediately.  So far this seems to be working with the 2 linked accounts I tried.

@user_14ukv9​ Most MUAs (like Outlook) require that you change the password in two places.  Both your Incoming and Outgoing/SMTP settings.

We did update passwords everywhere and were able to get email but not send.

Do you use a VPN, if so, turn that off, and I bet it works then.

Sorry, but I do not use a VPN.

Looks like Xfinity is also not allowing outgoing mail via my iPhone, either. Just attempted a test and it too failed to send. Hopped off my network and WiFi and it sent with zero issues from my phone.

It's the same network with the same settings I have had for multiple years with no issues until recently.

@user_q30vwm​ It might be that you other device(s) with an improper password.  Could you send me a DM with the username on your devices that you're having problems with?

@Reece12345​ Please DM me with the account that is having an issue, and we'll take a look.

@user_0ozxjl​ That's not true at all.  I'm sorry you were misinformed at the store.  You can certainly use third-party email clients.  If you'd like to DM me, I can try to take a look.

So, what is going on?   I never had this problem until about a month ago.  It's touch and go -- sometimes I can send email and other times I can't, and I continue to thet message:  "The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP)."  I have this problem using Outlook on my computer (using Outlook 2021) and also when checking mail on my iPhone 11.  I have tried changing settings in my mail client and putting in password again, but nothing fixes it.  I spent about 2 hours on the phone with an Xfinity technical person and we tried all kinds of fixes -- nothing worked.  So I am probably going to get a Spectrum email account (my internet provider) so that I can get good support and hopefully I won't continue to have issues.  I  hate to do that because I have had my Comcast email address for ages and I will have to spend alot of time changing it.

@dmc3sigma3 We have had no communication that our support with 3rd party clients is coming to an end. The error you are reporting is stating to contact your ISP. Since you've mentioned that you are currently with Spectrum as your internet service provider, have you already attempted to contact them and troubleshoot that error message?

@dmc3sigma3​ Our systems don't emit that message, that's coming from your client.  It sounds like a local firewall, but I can't be certain.  If you DM me with your username, I can take a look.

@user_kam241​ Please send me a DM.  I'll try to get you some additional information to help troubleshoot on your side.

Here's how to send a direct message (private message);

Click "Sign In" if necessary.
 
Click the "Direct Message" icon  in the upper right corner or https://forums.xfinity.com/direct-messaging 
 
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 the "Enter" key on your keyboard to send it.

See https://comca.st/3KQF8q9 for an example.

@XfinityAlex​ Over the weekend, I discovered a "Windows Mail" account on my PC with a bad password. I corrected that and have not had an issue with sending mail from the Outlook client since that fix and my experience has been that each weekday the past week, sneding email from Outlook was a no-go.

The instructions for sending you a DM listed above were a dead-end. Perhaps because I'm not really a Comcast/Xfinity subscriber anymore.

In any event, for the time being at least, this is not an issue for me. Thanks for the replay.

I don't know how I wound up as user n6j2g8, but this is the real me.

Same prob and deleted and added Comcast.net email to my outlook and is working again at least for now

It's beyond annoying that this is still going on. I've been through everything. I have no old passwords pinging Xfinity, but all of a sudden I will be unable to send outgoing mail. Most times the issue pops up when I'm trying to send anything with an attachment. And no, no VPN or anything of the like. And yes, my internal Xfinity settings are good for third-party email clients. And yes, all settings on Outlook 365 are good. Yadda yadda, different day, same issue with no end in sight. If I reboot Starlink, poof--issue goes away. For a day.

Hello, user_q30vwm! Thank you for reaching out for further assistance with the emails sending using Outlook 365. We are happy to help!

Do you get any error messages when the emails will not send or do they just sit there?

How long ago did this issue begin? (This time as I understand from your message this happened before.)

What type of device(s) are you using to send the emails in Outlook 360? 

I am having the same problem with Outlook. I has been happening off and on for most of the year but has recently become much worse. I can receive email but not send from Outlook. Sending an emaiI results in a send/receive error and the email stays in the outbox until some time later when it eventually gets sent. I checked and verified all Outlook account settings. Xfinity webmail works fine.  Seems to be a server issue at Comcast.

I have Outlook set up for IMAP; does POP work better?
