Hello,

I would like to know when the OnMessageReadWithCustomHeader events will be available for Outlook on the web and the new Outlook for Windows. This feature is essential for our workflow, and we would appreciate any insights on its expected rollout timeline.

Is there an official roadmap or ETA for its release?

Thank you!
