[NF] Latest Outlook settings breaking default email interface

Our system has built into it a way to send us emails for error reports etc, pretty standard stuff.

It just references the default client, fills in the usual suspects, Send.

Apparently the latest Office 365 or whatever it is has a change or a setting that is preventing us from doing this.

We don't use Outlook here so I can't test anything, but are there settings that can be changed on the user end or Admin level that might help resolve this? I'd like to pass along to the client some things to at least give a shot.

TIA,
