[Email Archive] Differences Between "Header To / Header Cc / Bcc" and "Envelope To" in Search Criteria

Questions

Please explain the difference between "To / Cc / Bcc" representing the search conditions and "Envelope To".

Answer

"To / Cc / Bcc" are the addresses specified when sending an email.
"Envelope To" is the address to which the email is actually delivered.
Therefore, even if you search with the same address, the search results may differ depending on whether you specify "To / Cc / Bcc" or "Envelope To".
