Voting Buttons Message Header - Exchange Online 2013

Good day,

Is there a way to know what Message Header Exchange sets when voting buttons are used in Outlook?

Or is there a way to set a rule that if a message has voting buttons and external recipients are copied in that it stays internal?



Hi Oliver,

Since there is no transport rule to bypass the connector in Office 365 and no special information in the Message Header, it is not feasible to achieve the goal.
