According to documentation Wix Toolset Documentation WixBundleAction is a BOOTSTRAPPER_ACTION that is available in Wix Bootstrapper.
And as answered here: Wix Installer Forum I think you can try something like this:
<bal:Condition Message="This setup requires Outlook 2010 or 2013. Please install office and then run installer again ">
(Outlook2010Present OR Outlook2010Present64 OR Outlook2013Present OR Outlook2013Present64 ) OR WixBundleAction = 3
</bal:Condition>
By having WixBundleAction = 3
inside condition clause, the condition will only be true for installation, and will be ignored during uninstall.
Hope this helps.
