No one has asked if he is using Yahoo paid POP mail. Outlook can't be
used
with Yahoo free web mail. Test Settings button actually sends an
email. If
you don't actually receive the test email, it's not working.
For normal messages in the Outbox attempting to go to a non-existent
server, those messages would still be visible in the Outbox even when
the e-mail client errors if it cannot connect to a mail server. The OP
may be using a paid Yahoo Mail account and have POP3 access. The OP may
be using YahooPOPs with a freebie Yahoo Mail account to give POP3-like
access to the e-mail client. In either case, if the e-mail client
cannot connect to a mail server, the e-mail stays in the Outbox and it
is not hidden.
When sending an e-mail with a read receipt request, the
Disposition-Notification-To header gets added to that outbound e-mail.
This alerts the recipient's e-mail client that a read receipt was
requested (which can then decide on what to do about it: ignore, prompt,
reply).
The e-mail which had the read receipt option enabled (to add the
Disposition-Notification-To header) goes out through the Outbox. The
recipient gets the e-mail with its header noting a read receipt is
requested. In this case, say the recipient's e-mail client sends back
an acknowledgement. The sender now gets an inbound e-mail which is the
acknowledgement. Wouldn't the inbound acknowledgement e-mail get stuck
in the Inbox (instead of the Outbox)? And why would the sender's e-mail
client get stuck trying to send a message that it must have already
successfully sent if the acknowledgement is now coming back? If
anything, it would get "stuck" on trying to PULL the acknowledgement
e-mail from the POP3 (inbound) mail server, not when trying to PUSH new
e-mails out.
I would think that if the problem is with the e-mail client continually
retrying to *send* a message that is hidden in the *Outbox* then it is
the original outbound e-mail with the Disposition-Notification-To header
(i.e., the outbound e-mail that wants to issue the request to the
recipient ) that is causing the sticking. The help article to which
Brian linked says, "If you have read receipts that won't send, ...". So
the sticking is caused by:
- An outbound e-mail.
- That has the Disposition-Notification-To header added (to alert the
recipient of the request).
- And which is supposed to pass through the Outbox folder.
So what is getting stuck in the Outbox is the outbound e-mail with read
receipt *request*. It isn't for the acknowledgement being returned, if
ever. You may never get the acknowledgement but that doesn't fix the
prior problem of Outlook getting stuck trying to send the request. The
options on how to handle acknowledgements (ignore, prompt, reply) do not
apply because this is an outbound e-mail with the request, not an
inbound e-mail with the acknowledgement. Getting Outlook unstuck means
losing the e-mail message that you intended to send in the first place.
