TLMDMapiSendMail, Outlook and HTML

Whisper Computer Solutions

When I use TLMDMapiSendMail with Thunderbird, the HTML body I compose internally shows up as HTML in the Thunderbird compose window as expected.  However, this is not the case with Outlook 365.  It shows up as plain text (complete with all the HTML markup making it basically unreadable by the user).  I have confirmed that Outlook is set to compose email in HTML.  Any idea what might be wrong or how to trick Outlook?

MAPI interface does not allow change any settings of the client mail application.

Accounding to MS MAPI can't be used for HTML eMails (https://support.microsoft.com/en-us/help/268440/info-mapi-is-not-suitable-for-html-messages). So this may be intended  limitation by Outlook when eMail is created via MAPI (instead to Thunderbird).

Thanks.  So odd that less used and free email clients are better suited for HTML email via MAPI than the giant Microsoft Outlook.  MS should be embarrassed ;)

I'll take a look at the alternatives expressed in the link you provided.
