In mailto: syntax commas are used to separate addresses. You might try
that.

Also should
&subject=Test
Be
?subject=Test

Then

?&body=yourmessagehere

I can't test this right now, but I am thinking formal mailto: syntax.

Is it possible to specify more than just the To address in a new OWA
message?
I know that when I do

that will open up a new OWA message with as the To
address,
but is it also possible to specify the subject/body of a message too? I
have
tried adding &subject=Test but that does not work.

Thank you in advance.
