We have noticed that the Office Add-In API does not return contentType for the following file extensions when accessing a mail item from in the Sent folder of the Outlook 2016 Desktop client:

  • emf
  • dwg
  • cur
  • otf
  • woff
  • fla
  • zip
  • ras
  • snag
  • svg
  • tga
  • wfx

Is this intended behavior? If it is a bug where do we report it?

This is a bug. We will open something to fix this in a future version of Outlook. However, some notes:

  • In your list, I do not repro this for "zip", it returns "application/x-zip-compressed"

  • When we fix the bug, it will likely behave the same as OWA. So if those types return a value in OWA, then it will return a value in desktop, if it does not then it won't. We will also look into adding those types into OWA as well.

  • I do not have a time frame of when this bug will be fixed.
