How To Modify Recipients of Exchange Global Address List


View products that this article applies to.

Summary

This article describes the steps necessary to open the Exchange Global Address List (GAL) for modification. It also describes how to modify a property of a given recipient in an Exchange Global Address List.

More information

The following steps are necessary for modifying a recipient in the GAL:
  1. Open a MAPI session.
  2. Find the entry id (PR_ENTRYID) of the Address Entry to modify.
  3. Call OpenAddressBook from session object.
  4. Open the root container of the Address book by calling IAddrbook::OpenEntry and passing NULL and 0 as the first two parameters.
  5. Call IMAPIContainer::GetHierarchyTable to open the Hierarchy table of the root address book container.
  6. Call HrQueryAllRows using a restriction for the only row that contains DT_GLOBAL as the PR_DISPLAY_TYPE property.
  7. Call IAddrbook::OpenEntry using the PR_ENTRYID from the row returned from HrQueryAllRows to get back an IMAPIContainer object.
  8. Call IMAPIContainer::OpenEntry using the entry id of the recipient you want to modify.
Now that you have the recipient wrapped in an IMAPIProp interface, you can make any modifications to it as long as you have the appropriate permissions.

The following code sample illustrates the above steps.

The following .lib files must be statically linked into your project for this code to compile and link correctly:
  • Mapi32.lib (if building for 32-bit)
  • Mapi.lib (if building for 16-bit)
