Hi,

But If User () Acme com uses the Public Key from User () Beta com to encrypt.
Can I open this message using only the Keys I have Escrowed? 

no, as you don't have the corresponding private key (the one of user () beta com).


 
btw: I believe your SOL without that other key as it's encrypted with
it. Am I right?

no, it's encrypted with the public key of user () beta com.
To decrypt it you would need the private key of user () beta com.
As beta.com company/users probably did _not_ hand over their private keys to you (for escrow)...

thanks,

Enno
