Question:

What is the Approved Email behavior when a Vault server is down?

Answer:

The email is not sent when a Vault server is down.

The sent email record has Status = Failed.  The Status Details field is populated with the reason (Could not authenticate against Vault).

Note:  This is a temporary fail.  Once the vault is running, the email is processed and sent.  This occurs when the Veeva Process Scheduler job for Approved Email runs.
