问题
We are facing problems while uploading files via our o365 addin on Windows. In the compose mode, we launch a iframed app via a ribbon button. This iframed app which launches in a Desktop App Web Viewer allows users to upload files. The problem is that as soon as the users are done selecting the files they want to upload, the Desktop App Web Viewer crashes and we are back to the compose view. This happens intermittently but is frequent enough to be problematic.
I looked at some Office JS issues and came across this one but wasn't sure if this is related. I also looked at some Outlook logs but couldn't find anything useful. The error logs didn't say anything much beyond the code - 15003. There were some other informational logs around the timeline of the crashes, but I can't say for sure if those are related. One was related to Software Protection Service and the other one hinted at memory leaks.
If I use the app to upload files outside of the Office environment, the app never crashes (both in Edge and IE11).
Any insights on this issue?

We have fixed the bug and the fix should be available in build 16.0.13603.10000 or later. When an updated build is available depends on the release channel a customer is on.
