I've seen no problems with mail from MS, so how about you elaborate on your problems and what version of OD are you using?

Here's the exact issue that I just ran into with o365 mail and note this issue was reported 3 years ago. No fix yet.

https://github.com/trusteddomainproject/OpenDKIM/issues/73

Granted, is it Microsoft omitting ADMD on DKIM signatures but it's not like we cannot not do business with o365 customers. This particular issue was with one of my e-mail customers doing business with the secret service and that's the issue. You have high profile organizations using o365 and your customers don't want to hear that the problem is on their end. "What do you mean the problem is on their end? This is the secret service!. It's got to be your problem!".

Here's my OpenDKIM version and related info:

OK, 2.10.3 is what we use, if you can try that? or maybe you have?

But Microsoft should be doing this correctly, try NANOG there are a few MS guys I know on there, or if no response there used to be a MS guy on the mailop list, no idea if he's still there, that list is run by self important power tripping dictators so it should be a last resort port of call if your desperate, if it was google I could help much deeper :)
