Outlook certificate problems

Hi Experts,

since tonight I have problems in outlook 2010 with a certificate.
can you help me to repair this cert issue ?
The server in the backend is an EXCH2007 cluster.

The error message is in german and not in english, sorry for that.
I try to translate is....

Error: the name of the certificate is not valid or the name is different from the website.

Can you help me out to solve this issue ?

I tried to change the service with this cmd

Enable-ExchangeCertificate -Services IMAP, IIS, SMTP -thumbprint

But the services are not changed.
The command seems to be ok, no error message.
But when I check again get-exchangecertificate |fl nothing changed.

On my service I have enabled SMTP and IIS but how to delete one entry ?

Ok,

I have two certs:

mail.domain.local -> this email has the bindings SMTP,POP
mobile.domain.at -> this email has the bindings SMTP,IMAP,IIS

With this setting I have the error which you can see in the picture.
When I add IIS to mail.domain.local then OWA stopped working, because IIS is moved to the other cert mobile.domain.at

Is it possible to delete one of the SMTP bindings on these certs ?
I tried the command enable-exchangecertificate....... but nothing changed.

And I found out, in my certificates, no autodiscover SAN is inside.
Do I need this link inside my certs ?
If yes how to change this or add more SANs ?

MAS (MVE)EE Solution GuideCommented:
Yes you need autodiscover.domain.com in certificate as explained in my article.
Otherwise you will get this error.

You have to contact your 3rd party CA and ask them how to add.
They will explain to you.

-->Is it possible to delete one of the SMTP bindings on these certs ?
No you keep SMTP on both self signed and 3rd party certificate as it is recommended to have SMTP on self signed because it will be used for inter server communication.
