Hello,
I'm currently developing a solution using Office.js (Outlook Add-in) to help our users manage their emails more efficiently. One key functionality we would like to implement is the ability to access and process system-generated messages of the class "IPM.Report.*", such as:
Non-Delivery Reports (NDR / bounce-backs),
Delivery receipts,
Read receipts,
And other Exchange-generated reports.
However, it appears that these message types are either not accessible through the Office.js API or are being filtered out by the Outlook client. This significantly limits our ability to provide a complete and reliable experience for our users.
These messages are critical in many business scenarios:
Tracking whether important emails to partners or customers have been delivered,
Automatically detecting delivery issues,
Archiving or processing undelivered correspondence for compliance or operational reasons.
I would like to know if there is any existing roadmap or known workaround to access these messages via Office.js, or if support for these message classes could be considered in a future update.
Thank you in advance for your insights and support.
