Outlook Client Access with Microsoft Exchange 2013 Self-signed certificate

Hello,

I installed Exchange 2013 CU1 on Windows Server 2012.
I can connect to my mailbox using POP3 and IMAP4 by changing the logon type to Plain Text.
I can also connect using the Outlook Web App and Exchange ActiveSync.
I can't connect to my mailbox using Microsoft Outlook 2010. I could with Exchange 2010.
Does Outlook 2010 work with the default Exchange 2013 certificate?
I don't want to buy anything, is there a free way of making it work for testing purposes?

Regards,
Robbie.

If Exchange uses a self-issued certificate it is probably issued by the server itself which acts as a CA. Export CA's certificate (not the certificate used by Exchange but the certificate used by the CA) and import it in the PC's Certificate Repository under "Trusted Root Certification Authorities".

I did nothing with the certificates just did a clean install of Exchange 2013 CU1.

How do I get the certificate file I need to install on the PC from the server?

I installed the new certificate using Outlook Web App so I didn't get the warnings anymore

The certificate tells you who issued the certificate. The issuer is the CA. The CA could be the same server. You should export CA's certificate and import it on the client's machine repository.
BTW, you reported that the only issue is Outlook 2010 unable to connect to Exchange 2013. What kind of error do you get when trying to connect?

It says issued by server which is the name of the server.

How do I "export CA's certificate and import it on the client's machine repository"?
