Office 365 -- Wildcard certificate

I am running Outlook 2003
Windows server 2003 Enterprise Edition

We are doing a cut over to office 365

I was told that we must have a non self signed certificate to migrate the e mail accounts to office 365

We did buy a Wild card certificate Will that work ?

Now we do have a self signed certificate on the server at this point

If i replace that certificate with a wild card cert will that cause issue with the e mail that is running on the server now ?

A wildcard certificate will work with Exchange 2003. Assuming that Office365 is connecting to your existing exchange box, it should be happy with the wildcard cert, though testing is probably the best way to find out....

The way i want to do it is to make another name

What we have now is outlook.mydomain.com
I want to create outlook1.mydomain.com and then use the wild card cert to validate

But it will not let me add a cert See picture

You'd need to replace the current (self signed) certificate with the wildcard cert. I assume you generated the csr and private key using IIS originally? If so, you'll need to export the wildcard cert and it's key from the installation and then import it (replace current cert) from the installation taht you have pictured above.

out of curiosisty, is there a particular reason that you're creating the new outlook1 subdomain?

Because we are thinking if we replace the self signed cert it will cause issues for cell phone users or other users
