A search on this issue reveals that you might find a lot of suggestions on how to solve the problem. Here's a quite sensible link which might guide you further, written by Prashant, a Microsoft MVP for Office Servers and Service.

He shows how to go about to debug and finds the error of Trust relationship…. Saying ‘Could not establish trust relationship for the SSL/TLS Secure Channel.’ And he shows how to solve it. By no means sure, bur perhaps that could be the solution.

Hi, thanks for your suggestions, i like to show you, when we open a document directly from URL of OOS works, as you can see in the following images:

we check the logs as you suggest and search for a text Could not establish trust but nothing with this in the logs files.

Thanks,
Jhon

Please use the following code:

It will restart the Ms Exchange OwaAppPool.
