Determine EWS settings for Exchange 2007 server

Absolute novice looking for step by step instructions on how to determine what my Exchange 2007 server's "EWS" Settings are.
My overall goal is to get a linux Thunderbird client connected to our Exchange server. I'm told by the guy that he needs our EWS settings and I know nothing about it. I googled a bunch of articles but could not figure out what they were talking about.

I would hugely appreciate step by step instructions on this. My exchange 2007 SP3.

If he's asking for the EWS URL then he wants the public server name that you would use to connect to OWA. For example:

I have supplied that and it was not accepted by Thunderbird. From all the docs I looked at they talked about autodiscovery, and the cert name being different so I thought there was something else here.  Thanks,

Does your SSL cert match the public FQDN on the EWS URL?, for example.

How can I tell that for sure? I'm running on Server 2008R2. I looked in Server Certificates and I see one that I know is a legit wildcard * which I'm pretty sure is used by owa for But I also see a lot of Certs named Microsoft Exchange Issued to "MyServerName" and MyServerName.domain, these are issued by MyServerName (actual name of my server).
Michael OrtegaSales & Systems EngineerCommented:
If you access OWA does it show you're using the wildcard cert?

adamant40Author Commented:
Believe so because it is the only cert that matches
