Unsolved O365 Outbound email issue
-
Take at look at the certs using this. The cert for your vendor, not you.
https://www.checktls.com/TestReceiver
See if it shows a hint.
Like a problem with the cert or their root or intermediate cert. Or even, the wrong cert.

I had never heard of that site.. That is fucking awesome..
And proves there is a self signed cert. but that does not explain why MS still cares..

This is why, MS killed TLS v1. I think v1.1 was also killed.

@JaredBusch we use it a lot, I seem to do SO many cert tasks these days, Ugh.

That is not the problem. TLSv1 for SMTP works fine.
Nothing that Microsoft has posted affects SMTP. it affects connectivity to Office 365 form your browsers and apps.

can you add the cert tag to this post?
Or do we need a new thread with just that site in the OP to tag?

Glad you like it! It helps identify SO MANY issues....

For the record, even though I made the above connector and it failed to verify, I did save the connector. Apparently, that was enough as email is sending now.

So which connector is solving this - the TLS regardless of cert condition, or the No-TLS

I only left the TLS regardless of cert, so it has to be that one.
