Use this to create a new certificate:
Make sure you restart the WebAppPools mentioned in the documentation. It should take effect immediately but can take up to an hour to take effect.
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
as above error, however, i have already checked the certificate and it is normal, i also had done the same steps as suggestion by microsoft,
New-ExchangeCertificate -KeySize 2048 -PrivateKeyExportable $true -SubjectName "cn=Microsoft Exchange Server Auth Certificate" -FriendlyName "Microsoft Exchange Server Auth Certificate" -DomainName @()
Set-AuthConfig -NewCertificateThumbprint <新的证书ID> -NewCertificateEffectiveDate (Get-Date)
Set-AuthConfig -PublishCertificate
Set-AuthConfig -ClearPreviousCertificate

but when i accessed the ecp, the same error shown:
HMACprovider.GetCertificates:ProtectionCertificates.Length<1
how can i resolve the issue?

Are you sure the new certificate thumbprint is assigned to ECP and OWA virtual directories?
If so, you can try an IISreset, to restart all the web services, this error web page comes after you put the credentials for login to ECP?

Hi @老马 负轭 ,
Welcome to our forum.
Is ECP working now?
“While actually i had done it yesterday in accordance with Microsoft, but i didn't work. this morning i open the ecp again and find it working.”
After creating and deploy a new OAuth certificate to the Exchange server, you need to wait for a few hours for the ECP to work. It should take effect immediately if you restart IIS or recycle the Outlook on the web and EAC application pools.
