Jonathan, et,al,
If you are running Insider Fast build can you please see if you can report the issue by clicking File, Support, Contact support? That option to submit the issue is only in Insider builds. So far we have not had any support cases on this issue to escalate
for a fix. If you are able to do this please include the crash event from the event viewer. In the control panel search for Event Viewer. Open it and under Windows Logs locate the Application log and look for event 1000/1001 for the time of the crash.
That is the detail the product team will need to start and they will probably need addition information too.
Are you saying that the only way to report a bug is to run Insider Fast? To quote the Microsoft page, suitable for people that "don’t mind a bit of risk using unsupported builds". In other words, to get support I have to install unsupported software. That's
a little Machiavellian, don't you think?
Unfortunately I can't take that risk on a production machine.
Surely there must be a way to report bugs on supported versions of Outlook to the development team. The fault is easy to reproduce, I'm a developer and can deliver diagnostic information on request.
