Reinstalling Exchange Certificate - 28.Nov.2008 11:59:09 AM

We currently have Exchange 2007 setup, and we are allowing users to use OWA through our VPN connection.
We use a Sonicwall which allows us to do SSL VPN, which is nice and easy. However when i set up OWA it complains due to the RSA Key being 2048 bits and it only supports upto 1024bits. Does anyone know how to downgrade the Bits used within OWA.?

I have figured i need to remove the exchange certificate and reinstall one with 1024 bit key.

Can anyone tell me how i remove a key which is in use?
Also will me reinstalling a new one affect any of the users?

Exchange 2007 will use self certified certificates, you can change certificates to the self signed ones, using IIS Console, Directory Security, Server Certificate wizard for owa.

You can also, manage installed certificated using the Certificates.msc for the local machines (see under Certificates, Personal) to view and remove or install new certificates.

Are you using a SonicWALL SSL-VPN unit, or just establishing a VPN to a SonicWALL firewall? If the former, all their SSL boxes have an OWA feature built into them.
