There's a column "Size" in the list of messages.

When I remove attachments from a message, the size shown does not
drop -
even if the attachment was the bulk of the message. This seems to be
true, even if I quit and restart Outlook, emptying the bin as I do so.

In other email clients I've used, the shown size _does_ drop when I
remove attachments. So what gives?

1. Are the full emails - i. e. including the attachments - still being
kept somewhere? If so, how do you get at them?
2. If the answer to 1. is "yes they are but you can't", what's the
point
of the ability to "remove" attachments?

If I want to ditch attachments but keep the message, I remove
attachments, then copy the
message to another folder. The copied version has the reduced size
as expected. I can then
delete the original.

It's a 141KB message, that contained a 99K attachment. I deleted the
attachment. Still shows as 141KB in the inbox; interestingly, it still
shows a paperclip in the list of emails, though when I now look at the
email, I can't see the attachment.

I tried dragging it to another "folder", so a move rather than a copy,

But no change.

so I dragged it back. I then moved it (Ctrl-drag, I think). There is

Oops, I meant copied it.

now a copy in that folder, showing no paperclip. Good - but it shows
as 24 MB! (The original in the inbox still shows as 141 KB, paperclip,
no attachment visible.) I am able to delete the 24M one (it's in trash).

Closing and re-opening Outlook: gone from Trash, still in Inbox at
141KB, paperclip, attachment not visible.

Isn't there some way to export as a .eml ?

Maybe if you look at the raw .eml that would tell you
the true size at the moment for an item.

Then you could "vet" that 24MB item and see exactly
how it claims such a thing. Making 24MB from 141KB
is a neat trick (like, if embedded photos stored on
a server, were getting downloaded and placed "inline"
in the document, but that never happens, right?).

The MIME format has sizes for stuff, and it could be
the software is latching onto a field value there,
rather than doing any sort of maths on what object
is actually stored.

Whatever is going on, it sounds clever, and totally
unsatisfactory.
