KB203858 - How To Use the HrMailboxLogon Function

MORE INFORMATION

To work around this behavior, the last leaf of the message store must have a string that identifies the store name to be used (for example, "Microsoft Private MDB" or "Microsoft Public MDB"). The lpszMsgStoreDn must be in the following form:

/O=Organization/OU=Site/CN=Servers/CN=ServerName/CN=Microsoft Private MDB
or
/O=Organization/OU=Site/CN=Servers/CN=ServerName/CN=Microsoft Public MDB

The following code demonstrates how to use the HrMailboxLogon to log on a user's mailbox, and then return a pointer to this store.

Sample Code

In the following code, it is assumed that you have a valid lpSession and pointer to the default message store lpmdbDefault (the user's inbox), and that szMailboxDN is already set.

   (...)
   // Gets server distinguished name from current session - from edkutils.h
   hr = HrGetServerDN( lpSession, &lpszServerDN );
   if ( hr != S_OK ) {
       goto CleanUp;
   }
   strcpy(szServerDN, lpszServerDN);
   strcat(szServerDN, "/cn=Microsoft Private MDB");
   // Open user's mailbox using distinguished names
   hr = HrMailboxLogon(
           lpSession,
           lpmdbDefault,
           szServerDN,
           szMailboxDN,
           &lpmdbMailbox);
   if ( hr != S_OK ) {
       goto CleanUp;
   }
   (...)
