Users who were upgraded to Office 2016 have discovered they can't preview Excel files in Outlook's reading pane.
You can tell it is working because when you do a search in Outlook it will have a ‘we’re indexing right now, try again later’ type message and not the yellow bar ‘Something Went Wrong…’ message. Outlook, in particular, will only rebuild it’s index when it is running so make sure you leave Outlook up for a few hours.Anybody have an idea why this isn't working? I have also checked some Google searches to see what other people have had tried but no luck. I have checked the all of the add-in's to make sure that they where enabled. I have a user that has there outlook now previewing any excel documents.
