Enabled Outlook actionable's for Survey - not working for some domains


While configuring outlook actionable message for survey for giving the option for end user to submit the survey in the email, it does not work with all the different domains.

Release or Environment



It is most like an issue with your proofpoint  as it is the one which is bypassing/suppressing the actionable content. and thus not allowing it to be sent to other domains


Involve your exchange administrators in order to fix this as the proofpoint is on your side of the infrastructure.
