Hi All,

Since moving to Exchange 2007 earlier in the year, those using Outlook 2007 get the following error when they open Outlook.
Users still on OUtlook 2003 do not.
Users using OWA also do not.
We have not changed the site address except for the fact that /owa follows the url.
We have an SSL cerificate.

Any help would be greatly appreciated!

What sort of SSL certificate do you have?
Is it a single name certificate or a SAN/UC certificate?
Is it a commercial or self generated certificate?

Outlook will attempt to connect to certain URLs for certain information, even internally. That can generate the error that you are seeing if the certificate isn't setup correctly.

Thanks for the reply.
I am not sure if it is an SAN/UC - how can i tell?
It was purchased from Verisign - I would assume it's a single name? Generated req from within IIS on the actual server.

If the request was generated in IIS then you have a single name SSL certificate.
Exchange 2007 SSL certificate needs to generated through Exchange.

I outlined on my blog last year the full certificate process.

If you don't want to change the certificate then it is possible to configure Exchange to use a single name SSL certificate, but you must have the correct configuration both internally and externally. http://www.amset.info/exchange/singlenamessl.asp
