I have also been doing a little more playing - the issue might just
be that the destination nameservers (for mail.protection.outlook.com)
don't support EDNS.   If I do a query with EDNS disabled, I do get
answers - so for outlook.com the problem might be more technical,
rather than policy.

In general, all DNS queries munnari sends use EDNS.
