Office 365 smarthost 800B010F error

same error, with mail.boardmapsemail.com

You haven't answered all my questions:

23

Just to ensure the problem is NOT with the LE cert (100%).
Please do the following:
Start
Run
MMC.EXE
Ctrl+M
“Certificates”
ADD
“Computer account”
Finish
OK

Then find your LE cert.
Double-click it.
If it shows “You have a private key that corresponds to this certificate.”, then the cert is VALID.

And the problem is with Exchange and its’ mostly undocumented expectations/requirements.

24

Here is some external proof that the cert is VALID:

openssl s_client -connect mail.boardmapsemail.com:25 -starttls smtp
CONNECTED(000001B0)

-----END CERTIFICATE-----

You have two errors, neither of which is caused by the cert:

microsoft answer with ,550 5.7.64 TenantAttribution; Relay Access Denied [SN1NAM04FT035.eop-NAM04.prod.protection.outlook.com]

raised by 800B010F - The certificate’s CN name does not match the passed value.

30

That shows two certs for the same FQDN mail.boardmapsemail.com.
3624…
F8C6…

That may be another reason the powershell fails - when you say -FQDN “mail.boardmapsemail.com” which cert is chosen?
If you don’t need both certs, delete one.
Then try the powershell again.

31

I already tried it, does not help

32

Tried what?
Please be more clear.

33

make only one certificate, and setup Exchange edge server, on edge server also this error

34

I still see two certificates with that same name.

35

i does it yesterday.

36

So why do you have two certs with the same FQDN today?
Also, have you tried the powershell with FQDN autodiscover?

37

ok i try to upgrade to Exchange 2016. Thanks you!

38

That will probably have the same problem.
But good luck to you.
