Exchange Certificate

Morning everyone,

clients on XP and windows 7 (outlook 2010) have received a security Alert stating "The security certificate has expired or is not yet valid". The certificate has expired. I have created a new one, but they still get the same alert.

I have gone onto the server and deleted the expired certificate, but still they get the alert. I have picked one client to work on, I have removed the certificate from the client computer, rebooted, but after opening outlook the security alert returns.

Any ideas how to make the clients use the new certificate or at least stop looking at the expired certificate.

Thanks
JT

Have you already procured new certificate on Exchange server ?

In that case you need to assign exchange services such as iis to new certificate

If you haven't yet, please generate new certificate request from exchange to get new cert and once you get that install it on exchange server and assign exchange services to that cert

Yes I created a new certificate and assigned the services, it still looks for the expired certificate.

have you assigned certificate to all Exchange servers (CAS) ?

If yes, just close outlook once and reopen it and check

Have you enabled that cert for all the services?

Try: Enable-ExchangeCertificate -Services IMAP, POP, UM, IIS, SMTP -thumbprint <new cert>

Just try to open OWA and check if here you get same certificate expired warning ?

If here you get new cert, then I think just reboot the server once and check if it works
