16.11.1802200 Sandbox error

Split from this thread.

I have the same issue. It started for me when the auto-update installed version 16.11 (080220).

I haven't been able to log in and sync since early December 2017 - my account is a corporate one that uses client certificates to authenticate, and both Outlook and OneNote stopped connecting on Dec 3 2017. So that means that deleting the local cache of data is not an option for me, as I would lose 3 months worth of data.

I looked in the console app, and found 3 error messages from "sandboxd": I've posted the errors below, without all the gory details, which I can provide in some better way if necessary.

Error 1:
