How to create an out-of-office rule by using Extended MAPI

Summary

This step-by-step article describes how to create an out-of-office (OOF) rule by using Extended MAPI.

Collaboration Data Objects (CDO) 1.21 provides a simple mechanism for setting OOF text and turning the OOF state on and off. Because CDO 1.21 uses Extended MAPI, you can achieve the same results by using Extended MAPI code. This may be useful if you are already using Extended MAPI and do not want to mix MAPI and CDO.

Creating an OOF rule consists of two steps:
  1. Creating the OOF reply message
  2. Adding a rule to the rules table for the Inbox

Creating the OOF reply message

  1. Create a new MAPI message in the Inbox's associated contents table.
  2. Set the message class (PR_MESSAGE_CLASS) to IPM.Note.Rules.OofTemplate.Microsoft.
  3. Set the body (PR_BODY) of the message to the OOF reply that you want.

Adding an OOF rule to the rules table

  1. Open the PR_RULES_TABLE property on the Inbox by using the IExchangeModifyTable interface.
  2. Add a new row to the table with the following MAPI properties set:
    • PR_RULE_SEQUENCE
    • PR_RULE_PROVIDER
    • PR_RULE_STATE
    • PR_RULE_USER_FLAGS
    • PR_RULE_CONDITION
    • PR_RULE_ACTIONS
    See the following sample code for the required values.

Turning the OOF state on and off

The OOF state is held in the PR_OOF_STATE Boolean property on the information store. Setting the OOF state is as easy as setting this property.

Sample code

Note We do not recommend this code for use with Exchange Server 2007 or Exchange Server 2010. Additionally, this code will not work with Exchange Server 2013. When you use these versions of Exchange Server, you should set the OOF state by using the Exchange Web Services SetUserOofSettings operation instead.

For more information, go to the following Microsoft Office Dev Center website:

CreateOOF.cpp

This file contains code that demonstrates how to create an OOF rule and enable
OOF using Extended MAPI.

The relevant functions are CreateOOF, which creates the OOF rule, and
SetOOFState, which toggles the OOF state.

To build this code, you need to add the following files to your link settings:
- msvcrt.lib
- edkguid.lib
- edkmapi.lib
- edkdebug.lib
- edkutils.lib
- mapi32.lib
