Outlook 2007 ribbon not working in 2010

[Mark]

Hi, I have the following ribbon in my C++ Outlook add-in, which is
loaded when a contact inspector window is opened. It works perfectly
in Outlook 2007. However nothing appears in the ribbon in Outlook
2010. I verified that the XML is being returned by GetCustomUI, so
I'm not sure what the problem is.

This adds a group to the Contact tab after the Actions group, named
"Foo Bar", which contains one button.

<customUI loadImage="LoadImage">
<ribbon startFromScratch="false">
<tabs>
<tab idMso="TabContact">
<group id="dbCustomGroup" label="Foo Bar"
insertAfterMso="GroupActions">
<button id="foobarButton" label="Foo Bar"
size="large" image="foobar.png"
tag="fooButton"
onAction="ButtonClicked"/>
</group>
</tab>
</tabs>
</ribbon>
</customUI>

Any ideas why this isn't working in 2010?

Thanks,
Mark

Hmm. All my Outlook 2007 ribbon XML is working in Outlook 2010, including
contact customization XML I have in a couple of addins. See if removing or
commenting the <startFromScratch> tag line helps.

Do you have the Outlook setting to show any XML ribbon exceptions turned on?
Is that showing any exceptions in your XML?
