Transport rule condition to filter for BCC emails RRS feed

  • Question

  • When there is a bcc recipient in a email, the details of this recipient only lives in the "Envelope To" header field. When a transport rule is created in exchange to redirect the email to another user,

    the "Envelope To" field gets overwritten by the user@domain.com email address. The bcc recipient details is lost. There is no other place in the header where this information is stored.

    There are no rules under "Exceptions" which filters for emails that have bcc recipients either.

    Is there another mechanism that can be used to redirect the email to another address without loosing the bcc recipient details?

    To detect a BCC email, we could use the following logic.

    "The email address specified in the "Envelope To" header that does not exist under the To: or Cc: header fields"

    What would be involved to write code to match this condition and slot it in with the existing exchange transport rule format? 

    Thank You

  • Hello,

    I test it. If we set this rule as you said, the BCC recipient will not get message. And when we create a journal rule, we still can't see the BCC recipient.

    If we set the rule like this :from users that are inside the organization; BCC the message to addresses and redirect the message to addresses, the BCC recipient will get message. And when we create a journal rule, we can see the BCC recipient.

    In exchange server, there is no way to realize your goal.
