Recently, our company has switched to the OnlyMyEmail spam filtering
service, and about that time, received emails stopped being displayed
in HTML and are now displayed only in plain text. The "Read all
standard mail in plain text" option IS unchecked, so that can't be the
problem. Also, emails sent locally (from one of our email accounts to
another) are unaffected. Finally, the support page for Outlook 2003
lists this as a possible cause: "On the way to the recipient, the
message might have been routed through an e-mail server that doesn't
support formatted messages."

All of the above leads me to believe that the problem is on
OnlyMyEmail's end, but we've sent them an email and they've denied
that they're the cause of it. Has anyone else had a problem like
this, or is there something else that may be causing this problem?

Can you connect to the mail service via a web browser and examine the
message before Outlook downloads them? Can you temporarily disable the
service or is it a remote service that you can't control?
