Office 365 outlook.office.com / teams.microsoft.com / etc blocked #130

Hello, first off -- really impressed with what you've done with the DNS solution. However I'm having one issue -- seems to be when I try to log into any Office 365 items, such as Outlook (outlook.office.com) and Teams (teams.microsoft.com). These seem to redirect to their oauth 2 at https://login.microsoftonline.com, which is failing. Is this a known issue? I've tried logging out, clearing cache, etc, but don't seem to be having any luck. Please let me know if there is any additional information I can provide. Thanks!

After some more digging, these are the three domains requested:

I ran drill on these 3 sites from my local environment, and the one that doesn't seem to get a good reply is login.microsoftonline.com.

Tbh, this is not a known issue, and I cannot reproduce this.

I ran drill on these 3 sites from my local environment, and the one that doesn't seem to get a good reply is login.microsoftonline.com.

The answer is truncated, but this behavior is expected.

Try doing drill -b 4000 login.microsoftonline.com

I think you're actually right. It seems like another DNS tool I have in my chain (stubby), is actually the one causing the issues. I'll close this issue, sorry for the confusion!
