How does Outlook know what format to apply to an incoming email?

[Richard Lewis Haggard]

I'm a developer in a company that makes software that encrypts email
messages and am working on a bug that says that if an email was created in
Outlook in Rich Text format and has elements in it like a table then the
Rich Text formatting is lost upon receipt of the email. It looks like
Outlook is looking at the encrypted email and deciding that it must be text
and all formatting is lost. The actual data itself is still present in the
received email and is displayed in simple Text format but the Rich Text
formatting is lost.

So, the real question is 'How does Outlook know what sort of formatting is
to be applied to an incoming email?' Outlook is normally pretty good about
discriminating between text, rich text and HTML, but what is the mechanism
by which such logic is performed? What fields in the email let Outlook
determine what sort of formatting is to be used to display the email?

I apologize profusely for the duplication of items. My psychic powers appear
to be on the blink today and failed to notify me that www.outlookforums.com
and Microsoft.public.outlook.general were the same location. To ensure that
this is not an ongoing issue, I have made a reservation at Cambridge Museum
of Science's exhibition of radioactive spiders to get rebitten in the hopes
that this will boost my powers again. If that doesn't do it, Pilgrim Nuclear
Power is just down the road and they're usually pretty good about letting
people in to get a recharge on their gamma ray accumulation.
