This is quite a common problem but i can't seem to find a clear and concise answer for it:
We have migrated from a SBS2003 box to a new SBS2008. Mail has been migrated over successfully however when the users open up outlook it shows a warning 'The name on the security certificate is invalid or does not match the name of the site'
I can obviously click Yes to proceed and all works fine but we need to get this resolved.
If i view the certificate the issued to and issued by is sbs2008machine.internal.domain.
On the SBS2008 machine i go into EMS and go to get-exchangecertificate it shows 4 entries, the top one is showing as subject sbs2008machine.internal.domain.
In IIS on the bindings for the SBS Web Applications the SSL certificate is set to remote.internal.domain
We've done other bits to test this such as creating new certificates and enabling them for OWA use and SMTP etc but i think we've confused things along the way.
Can anyone give me a clue as to what we need to ?
