Bypass INKY in Microsoft365

There may be instances where you’d like a certain sender or recipient to bypass INKY altogether. You can follow the steps below to ensure these emails are bypassed by INKY.

 Instructions

1. Login to the Exchange Admin Center → Mail Flow → Rules

2. Hit the “+ Add a rule” icon then “Create a new rule…”

   Open

   

3. Set up the following parameters:

   1. Name: IPW Filter - "Your Name Here"

   2. Apply this rule if…: choose the applicable option for the type of mail you want to bypass INKY. In this example I’m bypassing Calendaring type mail

   3. Do the following: Modify the message properties, set a message header

   4. Set the message header “X-IPW-Ignore” to the value “True”

   5. If you need to add exceptions then you can do so now.

      Open

      

   6. Hit “Next” then set the “Match sender address in message” to the appropriate requirements for your mail.

      1. Header - Least secure as the header from field can be spoofed

      2. Envelope - Most secure but may not match everything you need

      3. Header or envelop - Most broad but just as insecure as header only

   7. Hit Next → Finish

   8. Find the newly created rule in the list and select it then select “Edit Rule Settings”

   9. Set the priority to the number directly after the lowest current filter rule. In my example, the lowest rule is the “IPW Filter - Encrypted” rule at priority 11 so I’ll set this new rule to a 12. Then hit “Save”
