Is it possible to reset the Exchange certs? I know the certs are linked with IIS so need to know if it can be reset.

Re-install, get the certs back to default. The issue that I'm having is that the out server was restarted last night and caused all my certs to become invalid. So want to start off fresh.

You check whether your certificate is there in the store

If it is there you enable services using the thumbprint of the certificate
example:  Enable-ExchangeCertificate -Thumbprint 5113ae0233a72fccb75b1d0198628675333d010e -Services POP,IMAP,SMTP,IIS

If your certificate is not there in the store, download the certificate from the CA (control panel)
Install the certificate and enable certificate using the below Links

If it is not, it could be that the date was changed in the server.

If this did not work, try to re-key your certificate.
Before importing the certificate please make sure you have internet in the server.

Thanks, had to re-issue the cert and reconfigure my firewalls to allow Exchange access to the internet without the use of a proxy. All working fine now.
