Alert users to communication failures between box and Office Online
Three times in the last two months, we have lost hours of edits to box files made in PowerPoint Online. Box’s position is that this is a communication failure on the Microsoft side: box passed the file to Microsoft and Microsoft failed to pass the file back. The edits made are lost with no recovery possible.
Since Microsoft has published its auto-save frequency for all of its integration partners (see https://wopi.readthedocs.io/en/latest/scenarios/coauth.html), could box implement a process to check for the auto-save in the window specified by Microsoft, and alert the end user if it’s not occurring? If box sees widespread failures, box could include it in the list of known issues on its website. Since box is not checking to see if files are auto-saving, it has no way of knowing when the issue is occurring as it did after a Microsoft break fix on July 23-24.
It would certainly seem that box is better equipped to do this than an end user who has no visibility into the communication between box and Microsoft or lack thereof.

This is a great idea. I'm surprised it isn't in place already.
