He can send fine on other machines when using rpc, owa, or mapi based connections. His client settings are appropriately configured, he's logging in as his fully qualified email address (which matches his UserPrincipalName), he's set for the proper authentication, he's set to authenticate before send - but cannot send to anywhere. This user (we'll call - whenever trying to send via smtp to any recipient (both internal and external) fails.

One of these 5 users has a mac and is using MacMail with IMAPs and SMTP. We set up the domain as an External Relay domain, added the accounts, mail flows beautifully between the orgs - that is for anyone using RPC, OWA, or ActiveSync based clients. A customer of ours, we'll call the domain "" for test purposes, is utilizing our split-domain where their domain has about 5 Exchange accounts, and the remainder of their employees are on an external linux pop mail server. This has been fine for us for a while - until I came across an issue I could not fix.

Our provisioning software sets up the domain as an "External Relay" domain. We recently started offering split-domains where some users are on our hosted exchange platform and others are either external or on a linux POP/IMAP solution. We host via HMC several domains with Exchange 2007. From what I'm told we have never had this issue before, it seems to be causing several email related issues.I have an interesting one that much searching has not resulted in an answer. I have access to the old CSR file used to create the last certificate, and the previous one was still on the server at the beginning of all this to confirm. In fact the only difference between the new and old certificate is the expiration date. The Problem is both the new and old certificate have a subject and SAN of. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If the connector's FQDN is not specified, the computer's FQDN is used. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default ServerName with a FQDN parameter of. Microsoft Exchange could not find a certificate that contains the domain name in the personal store on the local computer. Now we are getting the below error with the EVENT ID 12014: About a week ago another employee uploaded a new certificate through EMC. Our Exchange 2013 server certificate for our SMTP, IMAP, POP, and IIS services was set to expire yesterday.
