Sorry - did not see this in the documentation, and I'm trying to clarify for some internal user docs.
If you have "Easy Open" enabled, does a first time Cisco Secure Email Encryption Service/CRES user (recipient with no previous account) have to:
a) Use the attachment to create their user account (i.e., save the attachment and open it in browser to get redirected to res.cisco.com), or
b) Are they prompted to create a user account when they click the Read Message link (attachment not needed unless link validity time expires)?
Although we temporarily enabled the Easy Open feature to test (and now have it disabled), I already had an account for CRES - so could not verify the behavior.
TIA for any responses.
