Thank you, Scamp468.

Since there have been many posts on this subject, I felt should summarise what works for me. I am on iOS 14.4.
I don't like the idea of using the text app as I believe this just converts the message to an MMS, compresses the files and (in my case anyway) incurs extra charges.
Yes. «[U]sing the text app» does send the message as «an MMS», which gets converted to an email along the way to the email server destination. (Probably as soon as it leaves the phone network.)
The extra compression of the files is probably a simple byproduct of using MMS: it’s not intended for high resolution use.
The email that it gets converted to probably has no textual formatting, or even formatting of the attachments. It is probably a plain-text (text/plain) email. (Who knows what attachment method [Content-Type: multipart/related; or Content-Type: multipart/mixed] may be used for the attached images.)
This may suggest that a plain-text (text/plain) email might “kick” Outlook into “doing the right thing”™️ with the attached images.
Unfortunately, there is no guarantee.
In fact, even this workaround is fragile—subject to being easily broken by any tiny changes in the web of interactions involved in transferring MMS messages and emails—that could stop working at any time.
1.Attach a very short video with your photographs. This makes the photos present as attachments. The receiver just discards the video. Not everyone likes this way around so:
From N-K-O’s investigation, we know that this works by forcing the Content-Type to multipart/mixed, rather than the multipart/related Content-Type that is appropriate when all attachments are of the same filetype.
For whatever reason, Outlook doesn’t allow users to perform bulk attachment operations (such as bulk-saves) if the Content-Type is multipart/related. (If anything, the opposite would make more sense, if this had anything to do with “sense”. Instead, it probably, simply relates to a “kludge” in Outlooks email composition algorithms: why analyze whether all attachments are of the same filetype; just always use Content-Type multipart/mixed, regardless! Hence, if Outlook runs into Content-Type multipart/related it “knows” that it is dealing with non-Outlook content! [There are likely many more such “gotchas” in Outlook’s algorithms.])
Hence, the added attachment need not be a video, but any filetype that is different from the primary attachments.
2. Use a g-mail (or I presume any other non-MS/Outlook derived e-mail system) as your default sending account on your iPhone. The photos then display at the other end as attachments, seemingly even when receiving through MS Exchange. If they are not presented this way with an MS derived e-mail account, send to the g-mail account. This always works for me.
This workaround is why we know that there is a portion of the issue that involves Exchange servers.
Unfortunately, we know much less about the details of this portion of the issue.
However, it should be obvious to anyone that if it were not for the way Outlook prevents its users from performing bulk attachment operations (such as bulk-saves), based upon email characteristics known only to its programmers, this would all be a non-issue!
In other words, if Outlook (and its derivatives) were fixed, so it allowed users to perform bulk attachment operations of their received email with attachments, we need not bother with any vagaries with Exchange servers.
I am very definitely non-techy so I hope this helps some of us out there.
You have provided good help. Thank you.
