With Exchange 2013 SP1, a few "Apps for Outlook" are installed by default. I have not been able to get any of them to actually work... UNLESS I log into OWA from Apple's Safari web browser on Mac OS X. Safari on Windows loads the "lite" Outlook Web App which doesn't load "Apps for Outlook" at all.
OWA on Internet Explorer 11 lists the apps within the emails, but they don't work (see screenshot). The full Outlook 2013 desktop program lists the apps as well, but again they don't work at all.
Am I missing some sort of configuration on Exchange 2013 that gets these to work on Microsoft's web browser and email client products? It's kind of strange that they work on Apple's products so easily. I've tried Chrome and Firefox on Windows as well, but those don't work either.
