Mail flow/transport rules and subaddresses

I'm reaching the limits of my patience trying to solve something relatively simple in concept and am turning to the community to point me in the right direction.

 

Here's the problem: When an email hits our Exchange server (Exchange Online) from outside the domain and the recipient's address contains a particular subaddress tag I need that email BCCd to a shared inbox.

 

I've tested a variety of mail flow/transport rules in an attempt to solve this, and I can get them to fire if using some other criteria (ex. if a specific word is found in the subject line), but never as I outlined above. An example of one such failed rule: https://imgur.com/yH149TV

 

Thoughts, tips, tricks? Any help would be much appreciated. Thanks in advance.

      VasilMichev Thanks for the reply. I tried as you suggested and it works. However, if I'm not mistaken, this method doesn't make use of the +tag (subaddressing) as a condition for triggering the rule. Is that correct?

       

      Just for some added clarity, I'd like the rule to fire when the in-domain recipient address looks like: marketing+outreach AT domain.tld or JoeBlank+outreach AT domain.tld  ... really any time the "outreach" subaddress is used. Is that doable?

       

      Thanks again!
