Note: This is a self-answered question. It originally received no responses and may appear too broad as a stand-alone question. I discovered the answer myself and am leaving it in place in case anyone else runs into the same problem.
When attempting to send a message containing a specific URL, the message does not get sent to the addressee. Instead, a message from me, addressed to me, is delivered back to the originating inbox. It contains the original message as an attachment, and that URL is missing from the message body in the attachment.
It happens with any addressee. There is no error message, and everything else works normally.
The computer is running Win 7 Home Premium and Outlook 2007. The problem is specific to this single URL when it is typed into the body of a message as text: http://www.couponpreviews.info (which is a good, safe URL and a normal web site).
The behavior is a little like that URL is being quarantined as malware, but it is only being affected within Outlook (nothing blocks accessing it in a browser, and if I create a file containing it, the file is not quarantined).
If Firefox is used to open that URL, and then the "email link" feature is used, the same result happens (Outlook is the default email application).
As a test, I sent an email containing that URL from another computer to the email address on the affected computer. The message was received but only the "http://" portion of the URL appeared in the body of the message, the rest of the URL was gone.
Whatever is going on is obviously within Outlook, and some process has become associated with that URL. However, there is no Outlook feature designed to work this way. Outlook is virtually unchanged from the "as shipped" version; I have not set up any special rules or filters. Microsoft updates are current.
I've never come across behavior similar to this and an online search turned up nothing.
Anyone have any idea what might be going on?

@Scott, thanks. The last queue took awhile. :-) – fixer1234 – 2018-01-14T04:32:20.140
And now, a mere three months later, it’s time to congratulate you on reaching third place. :-) – Scott – 2018-04-08T00:56:05.443
@Scott, just curious where you found the Stewards' Club and stats. Is there a summary page somewhere or do you need to run a query? – fixer1234 – 2018-04-08T01:59:48.323
Well, I just made up the term “Stewards’ Club” for the people who have earned the maximum possible number of Steward badges (three on meta sites, six on most main sites, eight on [SO]). It’s easy to see who has the Reopen Votes badge from the Reopen Votes Stats page, and then a simple matter of checking the user profiles of the (currently six) people who’ve reviewed 1000 Reopen Votes to verify that they all have the other five Steward badges. I sort of got the idea from Anthon.
– Scott – 2018-04-08T03:01:40.247@Scott, one of these days, I'll delete this thread. :-) In the meantime, it's anchoring this discussion until a moderator cleans it up. You aroused my curiosity, and I continued this discussion in a chat room. Drop in.
