How can i open a .application file exported from Office 365 Exchange?

I'm attempting to export a user's mailbox using Content Search from Office 365 Admin. I got everything configured correctly and the search completed. I then attempted to download the exported results. the download had a .application file extension rather than a PST, which is what i was expecting. I copied the Export Key to the clipboard before downloading the results

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That's actually a click-once package, as in the application that will do the actual PST download. You need to use a browser that supports click-once though, read here:

You have to use Internet Explorer or Edge to really get that to work properly. Open up your search in one of those browsers and it will function better.
