Exchange 2016 - Hybrid - Exchange Delegation Federation certificate expired
Hi All Hope everyone is keeping well. The "Exchange Delegation Federation" certificate has expired on my Exchange 2016 server. Mail flow between Exchange Online and Exchange on-prem still appears ...
Navishkar Sadheo Good Morning,
had to do this once and I just followed this MS Doc:

HCW can only establish the FederationTrust but not renew the MFG cert. MailFlow won't be affected. This only has impact on the FederationTrust/OrganizationRelationship from onPrem to Exo.
