I can understand that this is outside of your support scope, however, I have contacted VMWare, who is the support contact for my SAN at my primary office. Their statement is that this is an Outlook issue.
As such, please direct me as to where I can make a bug report other than this forum, or elevate the status of this report, so that a software engineer can look at this, because otherwise I am afraid a solution will never be found.
On this post, in the last week, you have three unique reports of this issue, all of us seem to have tracked it down to an issue with an update to Outlook 2016 made recently. I suspect as time goes on, more and more will be looking for a solution.
Over the course of the next couple days, I will be attempting to incrementally roll-back my office updates in an attempt to locate the source of the issue. Should I find that, I will post that here as well.
