I can not connect outlook 2007 on windows xp to a new exchange 2013, I'm sure exchange works because many clients are connecting without troubles. The mail profile is set to the correct proxy address and I enable the "Negotiate Authentication" as all other working clients. I already verify that Outlook 2007 is up to date with the last CU. When I try to set up the mail profile I just get a "impossible to connect" but I think it can be a certificate issue. How can I very the certificate that outlook uses?
this must be the english version of the message: The action could not be completed. The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action.
