hyperlink to an existing Outlook mail message

In Outlook 2016, I'd like the body of a mail message to include a hyperlink to another, existing mail message.

The general idea is that message2 would have a link to message1, and anyone who's previously received message1 and is reading message2 could click the link to open their own copy of message1 (i.e., in their own Outlook inbox; no cross-mailbox permissions needed; link would only try to access the clicker's own inbox).

I know that setting the href to "outlook:ENTRYID" is a possibility. (Without the quotes, and of course substituting actual entryID for that placeholder.) But the value of ENTRYID changes when the message is moved to a different folder, and anyway is unique to "my" mailbox (and wouldn't work for recipients of message2).

And I've learned how to get the PR_SEARCH_KEY of an existing email (thanks to this article).

But an href of "outlook:PR_SEARCH_KEY" doesn't work / target can't be found.

Finally, I've read that "outlook:GUID" works. But I can't figure out how (in Outlook VBA) to get the GUID of an existing email.

Does anyone know how to programmatically (VBA) get the GUID? Or convert PR_SEARCH_KEY to be a GUID? Or (back to my root question) any other way to create a hyperlink to an existing Outlook mail message?

The hyperlink only needs to work from within Outlook 2016 itself (so no concerns about the "outlook:" protocol not being recognized elsewhere on my computer).

Thanks very much.

How are message1 and message2 related? Part of the same conversation? – 0m3r
Not necessarily the same conversation. More like I sent an email a couple weeks ago, and now (separate conversation) a question has come up that I discussed in detail back then. So I'd like today's email (message2) to have a hyperlink (or anything easy for the recipient to click) that opens the old email -- assuming of course that message1 is still in their mailbox and they haven't deleted it. Of course I can always say "please find that email I sent" and give them subject/date/etc location info. But it'd be much nicer to say "please click here to see details from two weeks ago". Thanks. – Aboat

There is no other unique ID; PR_ENTRYID and PR_SEARCH_KEY are the only ones. However, you can use the email subject. See the following KB article: https://support.microsoft.com/en-us/help/158135/ol97-using-hyperlinks-to-access-outlook-folders-and-items. Also see: Using Outlook Links.
