Cannot send outgoing email from Comcast email address via Xfinity App or Outlook via cable internet wifi
But I CAN Send them fine from OUTLOOK and APP if I am on Cellular DATA network
On my Wifi (medicom cable connection) using the Xfinity Connect APP -Incoming messages are fine but Cannot send emails starting this morning, incoming emails are fine. Get error message that says :
Xfinity Mobile encountered an error. Please try again later. Message moved to draft.
If I take my phone OFF wi-fi and just use Mobile Data, the outgoing messages go though and no error message.
Also am having issues sending from outlook on my laptop, get two different error messages - one is a Server responded 421 resomta-po- 11v.sys.com when I try o test from outlook settings. Other is Sending ' reported error (0x800ccc67) :'The server responded: then a bunch of funny characters...
Incoming emails are fine. This just started this am. I did not change anything on my end. If I connect to a HOT SPOT with my cellular plan- everything works fine. Talked to three diffrent folks at comcast, "help," line and all said I should just keep on re-installing apps and software until I am blue in the face since they have neither the ability nor inclination to offer any real assistance in this matter...Everything works fine on Cellular data -there just appears to be some sort of conflict with the outgoing SMPT server and my cable internet wifi that wans't an issue until this morning. I did try removing my firewall on my internet secuirty program and that didn't help.
I am a chicken...that is afraid to mess with my IP address. My problem is only when sending an email on my cell phone using the mobile xfinity app, and the emails will get this error, and will go to my OUTBOX, not my drafts as it tells me. But if I go to my outbox, and resend the FAILED email, it will then work. I don't get this problem all the time..but in clumps..some days it is just fine. But I guess I'd rather go to my Outbox and resend vs mucking around with my IP..but it is driving me CRAZY. I just wish Comcast would address and fix the issue.
Altho I AM a real IT person, this odd problem has been confounding me for weeks. And I never relish the idea of calling Comcast.
But your post gave me an idea and Voila it is now solved, thank you! I was using a VPN which among other things CHANGES my ip address. When I changed its location, problem solved. Thx so much for the idea.
