Messages stuck in Outbox - actually a Comcast mail client issue

Yesterday I sent four messages to my wife. She has received probably 30-40 total emails based on those four messages. I had this problem once before. In both the previous case and the current case, the emails contained JPG attachments.

I was unable to delete the messages in the Outlook Outbox, even after I deleted the Comcast OST file, and Outlook rebuilt my Inbox and related folders.

In both cases, I solved this problem by going to Xfinity website and accessed email. I deleted the Outbox messages, Then suddenly those problem Outbox messages disappeared.

I'm sure that this issue is due to a bug in Xfinity email. In the past, I have actually written paper letters to Xfinity, on JFK Boulevard in Philadelphia to ask that bugs be fixed. I got responses denying there was a bug, but then a few weeks later the bug "mysteriously" disappeared.

I'm getting pretty disgusted this Xfinity. I have their Quadruple Play service. but the only service that is issue-free is Comcast Voice (VoIP) I am aware that "sometime soon" email service will be discontinued. Their Home Security service has lousy support and overcharges for replacement door/window sensors.

You send the messages from Outlook and they were in an outbox at Comcast?

Do you use send immediately or have a scheduled send?

Typically, when you send using classic outlook, you can't delete mail that is waiting to send unless you go offline or use mcfmapi. You'll get an error message that it is sending if you try to delete it.

I’ve had a similar issue recently with Comcast and Outlook. Messages with attachments just sit in the Outbox, and nothing clears them unless I log into Xfinity webmail and delete them there. Seems like Outlook is trying to send, but something on the Comcast side gets stuck. Looks like a server-side problem.

I am the OP. I have run into this problem repeatedly, recently, always with messages with attachments. In one case, my wife received 47 (!!) copies of the same message with attachments. My solution was to put Outlook Send/Receive into Offline mode, and then delete the offendin message from the Outbox.

With Comcast, I have noticed multiple problems that are repeatable. I have even written letters to the Office of the CEO, only to receive a curt dismissal. In one case, when I was on the phone with second level support, the rep did not know that Outlook is an email client. You can't make this stuff up.
