Word 2007 Ribbon appears in Outlook 2007 Email Message

[Kristi]

We developed a com-addin for Word and Outlook 2007. The addin creates a
Ribbon Tab in Word and a Commandbar in Outlook. On development and client
workstations the Ribbon only appears in Word and the Commandbar only appears
in Outlook. This is how it should be. However, on several workstations at
one client site the application loads correctly in Word, but in Outlook there
is no command bar and in an email message the Word Ribbon for the addin
appears. In Outlook the com-addin is an Active Addin, with no errors, but is
not functional.

This site has implemented many Office addins. Some are 2007 compatible and
some are legacy applications. In the Outlook email message the Add-ins tab
appears with Word legacy addin options.

I did not think it was possible for Outlook to automatically display Word
Ribbon items. Could it be that the legacy applications that create the Addin
tab in Word are forcing the Addin tab and other Word add-in Ribbon items to
display in the Outlook email message?

We cannot replicate this behavior on development machines and do not have
access to some of the legacy applications to install. PMLink and Adobe PDF
Maker 7.0. Of course the client does not want to un-install any of the
Office Addins or legacy applications.

Any thoughts on what could cause this behavior?

Additional information: In Outlook the com addin appears to load but the
OnSend event is not trapped. It is as if the email message with the Word
Ribbon items is only responding to Word events.

There's no way to tell what's going on without testing and analyzing the
code. However, I would never combine both Word and Outlook addins in one
project. That can cause all sorts of problems depending on the user
configurations.

Question. Why would you want to implement the ribbon for Word but not for
Outlook email Inspectors?
