451 4.4.0 Primary target IP address responded with: 454 4.7.0 Temporary authentication failure - Exchange Edge

The error doesn't suggest anything that could point you to a solution.
In my case it wasn't the KB article found here.

Turned out to be a certificate Service assignment that got lost.

The error in the Eventviewer was:

EventID: 12023
Level: Warning
Task Category: Transportservice
Source: MSExchangeFrontEndTransport
Microsoft Exchange could not load the certificate with thumbprint of BAE49XX5021785XX4433FXXA78XX434CXXBD4EXX from the personal store on the local computer. This certificate was configured for authentication with other Exchange servers. Mail flow to other Exchange servers could be affected by this error. If the certificate with this thumbprint still exists in the personal store, run Enable-ExchangeCertificate BAE49XX5021785XX4433FXXA78XX434CXXBD4EXX -Services SMTP to resolve the issue. If the certificate does not exist in the personal store, restore it from backup by using the Import-ExchangeCertificate cmdlet, or create a new certificate for the FQDN or the server enabled for SMTP by running the following command: New-ExchangeCertificate -DomainName serverfqdn -Services SMTP. Meanwhile, the certificate with thumbprint XX728XXD9AD2D55XXE9F9D4BEXX8949AE4DXXCBA is being used.

Overwrite the existing default SMTP certificate?

Current certificate: 'BAE49EF5021785CA4433F25A7800434CA4BD4E6E' (expires 21-11-2017 13:51:22)
Replace it with certificate: 'DA9D8609DED5198F1AEEE96E3CCE33ED7323DA5E' (expires 26-9-2020 14:12:44)

As soon as I ran this command mail flow started again.
