Read Receipts

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release. Read receipts are report messages similar to delivery and nondelivery reports. They have message class strings of the form REPORT.X.RN, where X is the message class of the message the receipt corresponds to (usually IPM.Note). Read receipts inform a sender that a recipient has read a message. Read receipts are generated by the e-mail client software of the recipient. No other component of a messaging system can be guaranteed to know when a user opens a message.

Whether a gateway can support read receipts depends on the capabilities of the foreign system. If the foreign system does support read receipts, gateways should perform the following tasks:

  • For an outgoing message, the gateway should convert the value stored in the PR_READ_RECEIPT_REQUESTED property of the message into whatever format the foreign system requires for read receipt requests.
  • For an incoming read receipt, the gateway should convert the content of the receipt into a message of the message class REPORT.IPM.Note.RN, and deliver this message to the sender of the original message.

For more information about the properties required on read receipts, see About Message Properties in the MAPI Programmer's Reference Online link.
