Options tab for old add-ins in Outlook 2010

I’ve been using an add-in in Outlook 2007 (and previous Outlook version) which added its own tab in the Options dialog of Outlook to configure it.

I’ve now upgraded to Outlook 2010 and the add-in still seems to work just fine but I can’t find its configuration tab anywhere. It hasn’t been added as an extra section in the new File-> Options dialog nor can I find anything on the Add-Ins tab of the Ribbon.

How can I configure it in Outlook 2010 or should I look for a new add-in?
