How to know if Exchange oAuth Metadata is refresh

Hi,

 

I have an environment with Exchange 2013 hybrid coexistence with Exchange 2019 now. oAuth is enabled.

 

I am suspecting the current environment, servers won't refresh the oAuth Metadata themselves. Is there any logs I can trace that? What event ID indicate the metadata is updated?

2013
2019
Exchange Server
hybrid
office 365

    Run the PowerShell command Get-OrganizationConfig | fl OAuth and check the NextCertificateUpdateTime field.
    Force a refresh directly:

    Set-OrganizationConfig -RefreshServerCertificates
