Within an Outlook Addin I am currently capturing when a user clicks the Recurrence Button for Series using this XML:
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
<commands>
<command idMso="Recurrence" onAction="RecurrenceButtonClick"/>
<command idMso="RecurrenceExplorer" onAction="RecurrenceButtonClick"/>
</commands>
</customUI>

I have not found the control-id in the Excels provided by Microsoft:
