Exchange Server Certificate error with thumbprint
I had install SAN certificate initially using Exchange command shll - new-certificate command with multiple domains for owa and active sync. This certificate didn't work with activesync so I deletedthat certificate and created new certificate using IIS one for my internla dowmin and othe for my external domain. After that my owa, activesync is working fine but I am keep getting this error in Event log: Microsoft Exchange could not load the certificate with thumbprint of 37FCFCB5AD720AE39E1A37C9AE45A3C22ED9E95E from the personal store on the local computer. This certificate was configured for authentication with other Exchange servers. Mail flow to other Exchange servers could be affected by this error. If the certificate with this thumbprint still exists in the personal store, run Enable-ExchangeCertificate 37FCFCB5AD720AE39E1A37C9AE45A3C22ED9E95E -Services SMTP to resolve the issue. If the certificate does not exist in the personal store, restore it from backup by using the Import-ExchangeCertificate cmdlet, or create a new certificate for the FQDN or the server enabled for SMTP by running the following command: New-ExchangeCertificate -DomainName serverfqdn -Services SMTP. Meanwhile, the certificate with thumbprint EF38D0D29B4FC0206704EF867616ECFF1FAFD097 is being used. I have removed 37FCFCB5AD720AE39E1A37C9AE45A3C22ED9E95E this certificate from Exchange, its still trying to get the same. Below is the certificate detail of my exchange server.[PS] C:\Documents and Settings\Administrator>get-exchangecertificate Thumbprint Services Subject---------- -------- -------46BD6A72B0048E793D903B22D30BC8D0B4B5D290 .....

My understanding is that you deleted the cert from the IIS. Try deleting ti from the cert store. And i am sure this is a notification, and will not hamper the functioning of owa and active sync. So you can ignore themRaj
