How to avoid replying to a mail when I'm in blind copy

Question

I'm working with Microsoft Outlook 2016, and I just received a mail where I've been put in blind copy. This is quite dangerous because the people in the To and CC list should not be able to contact me, and when I reply all to this mail I risk exposing my e-mail address to those people, which I don't want.

In order to avoid this, I'd like some message box to appear whenever I press the Reply all button of an e-mail where I'm in blind copy.

I've just checked the rules and I don't find a way to get this done, and creating a rule for marking such mails in some way also seems not to be possible: here are the relevant conditions for creating rules I've found:

sent only to me
where my name is in the To box
where my name is in the Cc box
where my name is in the To or Cc box
where my name is not in the To box

As you see there is no where my name is in the Bcc box (which would be what I need).

I can invent a workaround, like creating another inbox, using the where my name is in the To or Cc box, redirect all mails to that inbox, so that all messages in blind copy stay in my regular inbox, but I don't like this workaround.

Does somebody have an idea on how to help me?

Answer 1

You also have an exception "except if my name is in the To or Cc box", that should work.

The result of such an exception is a rule, which looks as follows:

The message, shown when such a message arrives, looks as follows:

Answer 2

I'd like some message box to appear whenever I press the Reply all button of an e-mail where I'm in blind copy.

I notice this in the last couple of days, I do not know how long it has been deployed.

Currently with Outlooke 2016, if you click reply all to a message you have been blind copied, you get the message.

Your address was hidden when this message was sent. If you Reply All, everyone will know you received it.
