Hi Yasser,

Base on my knowledge, you had lost the "Microsoft Exchange Server Auth Certificate", try the following step and check the result:

1. New-ExchangeCertificate -KeySize 2048 -PrivateKeyExportable $true -SubjectName "cn= Microsoft Exchange Server Auth Certificate" -DomainName "*.yourdomain.com" -FriendlyName "Microsoft Exchange Server Auth Certificate" -Services smtp

Do not accept to replace the SMTP certificate when prompted

2. Note the thumbprint of the new certificate. Let us assume it is 9D27633D94999CB5820E6559569BF3538BB07278

3. $a=get-date

4. Set-AuthConfig -NewCertificateThumbprint 9D27633D94999CB5820E6559569BF3538BB07278NewCertificateEffectiveDate $a

Accept to continue despite the fact that the certificate effective date is not 48 hours into the future

5. Set-AuthConfig PublishCertificate

6. Make sure to remove any potential reference to the previous certificate (which might not exist anymore) by doing Set-AuthConfig -ClearPreviousCertificate.

Best regards,
