Event 2008 MSExchange OAUth

Question

After recreated oauth cert i get plenty of Event 2008.
I have an Exchange 2019 server with hybrid Exchange Online

Event 2008 MSExchange OAUth

When retrieving metadata from the url 'https://login.windows.net/domain.onmicrosoft.com/federationmetadata/2007-06/federationmetadata.xml', different certificate(s) have been found.

I have run Get-Federationtrust | Set-FederationTrust –RefreshMetadata
it says that the command completed successfully, but no settings of 'Microsoft Federation Gateway' have been modified.

I check oauth connection and both sides were succesfull.
I have read about
Get-PartnerApplication Remove-PartnerApplication <application name>

.\Configure-EnterprisePartnerApplication.ps1 -AuthMetadataUrl '<url>' -ApplicationType <type>

But I don´t know about the inputs thou it seems to be correct.
Get-PartnerApplication

 

Name            ApplicationIdentifier                Realm UseAuthServer Enabled

----            ---------------------                ----- ------------- -------

Exchange Online 0000000x-0000-0xxx-xx00-000000000000       True          True

Microsoft Graph 0000000x-0000-0000-x000-000000000000       True          True

Does anyone have any ideas or links so I can move on. It's very annoying but despite this it doesn't seem to affect the users.

Hi，@Michael Wiskman

Thanks for posting your question in the Microsoft Q&A forum.

When you run Get-Federationtrust | Set-FederationTrust –RefreshMetadata, it says that the command completed successfully, but no settings of 'Microsoft Federation Gateway' have been modified. This is expected behavior, you just need to wait 24 hours for the command to be modified.

Regarding the issue where users got a lot of Event 2008 after recreating the oauth certificates, I found that other users also reported this problem. This is an event that can be ignored and will not affect user .It is recommended that you run Get-Federationtrust | Set-FederationTrust –RefreshMetadata to temporarily stop the message.

Here is what other users are saying: Event ID 2008 warning from Event Source MSExchange OAuth appearing randomly - Microsoft Q&A

If my answer is helpful to you, please mark it as the answer so that other users can refer to it. Thank you for your support and understanding.
