Outgoing email in iPhone is not working.

Yesterday I updated my password for my Comcast account. I updated it on my iPhone as well but my outgoing emails are not functioning. I did go into set up for email. Collect advanced clicked on the outgoing server and tried to update the password. The system verifies forever and then times out. Please help me. I’m trying to get some important emails out.

Hello @user_b029be, and thank you for reaching out on the Xfinity Community forums with your concern!

I can understand how frustrating this is, especially when you have important emails you’re trying to send and everything was working before the password change.

Since the issue started after updating your password, I’d first recommend confirming that you can send an email successfully through Xfinity Email in a web browser. If that works, it would help narrow this down to the settings saved in the iPhone Mail app.

For the outgoing server on the iPhone, please confirm the following:

Outgoing server: smtp.comcast.net
Username: Your full Comcast.net email address
Password: Your newly updated password
Port: 587, or 465 if needed
Encryption: TLS/SSL enabled

You’ll also want to make sure third-party email access is enabled within your Xfinity Email settings, since Apple Mail requires this access.

If webmail works but the iPhone continues timing out while verifying the outgoing server, that distinction will be especially helpful in narrowing down the next steps.


Please let us know if this helps.

Server password.  This happened every time you force a password change and yes I have done all the above. .

I had to delete my mail on my iPhone and reinstall. Tech told me it might take overnight before everything worked properly.  Still can’t see sent mail and sending mail works sporadicly.  It’s been 24 hrs.

In some cases that may be happening if the Xfinity.com settings, are not configured to sync your mailbox to the third-party applications like Mail for Apple. Here is some information on that:

To sync your Xfinity email on an iPhone using IMAP, first ensure that your account is set up correctly. Go to Settings, tap Add Account, then select Other and Add Mail Account. Enter your Comcast email details and tap Next. On the IMAP screen, enable Mail and Notes, then tap Save. Ensure that the Delete from server option is set to Never before starting. Note that if you previously used POP and deleted emails from the server, those emails won't be available in the new IMAP setup.

 

Please let me know if this helps.
