When I try to connect Outlook with RPC over HTTP, Outlook Anywhere, I get certificate errors.

With https://www.testexchangeconnectivity.com I did a test RPC/HTTP connectivity and I got the following error:
     The certificate chain couldn't be built. You may be missing required intermediate certificates.

Do you have a CA in your network that you are using for the certificates or are you using Exchange's self-signed one?

Ok found on the web page of my certificate provider "Xolphin" the how to for exchange 2007.
The root cert and intermediate cert of Thawte were missing.

The instructions in Dutch can be found at:
https://www.sslcertificaten.nl/knowledgebase/Exchange/Exchange_2007_-_Installatie_certificaat

The root and intermediate cert had to be downloaded and installed
Again in Dutch:
https://www.sslcertificaten.nl/knowledgebase/IIS/Microsoft_IIS_-_Installatie_root_en_intermediate_Certificaten
screen shots are of English certificate manager.

https://www.testexchangeconnectivity.com passes now all tests

That's good to hear.  You can now also connect Outlook using Outlook Anywhere/RPCoHTTP?
