Exchange certificate not updating? Connection test showing old certificate.

[DCUK6]

Hi,

 

Trying to move from exchange 2003 to office365 for education.

 

I'm using the Microsoft connection tester to try and get RPC working.

 

The original certificate installed by the previous tech was meant for another server so had the wrong address.

 

I've now installed the certificate feature on the server to create a new certificate just to get things rolling.

 

Went into IIS and and changed the certificate on the default website to the one created when it installed the certificate feature.

 

Have waited 30 mins after restarting IIS and now retrying the connection test but it's still coming back as the host name not matching the name on the certificate.

 

Any ideas?

 

Many thanks

Signed up to a ssl trial as apparently self signed certificate don't work.

Still no joy though.
