You have a hybrid deployment that contains a Microsoft Exchange Online tenant and an on-premises Exchange Server 2019 server named Server1.

Server1 uses a certificate from a third-party certification authority (CA). The certificate is enabled for the SMTP service. You replace the certificate with a new certificate.

You discover that delivery fails for all email messages sent from Server1 to your Microsoft 365 tenant.
