How to disable read receipt? RRS feed

  • Question

  • Hi, Guys:

    I am working on a C# VSTO plugin for Outlook 2016. One task requires a read receipt should not be sent for some types of incoming emails. Does anybody know how to disable read receipts by using C# and VSTO model?

    Thanks,

    Michael

  • You can set the global option in File | Options | Mail | Tracking.

    If you need to disable read receipts on the per-item basis, you would need to either use Extended MAPI (C++ or Delphi only) and call IMessage::SetReadFlag(SUPPRESS_RECEIPT) or use Redemption (any language) and call RDOMail.MarkRead(true).
