This article describes a new MAPI interface that you can use to retrieve mailbox tables on a per-store basis in Microsoft Exchange Server 2003.

Back to the top

When you use the IExchangeManageStore::GetMailboxTable method or the IExchangeManageStore3.GetMailboxTableOffset method to obtain the mailbox table from a server that is running Exchange Server 2003, the mailbox table that is returned by these methods appears to contain some duplicate rows. You experience this issue if a recovery storage group is mounted on the server on which you run these methods.

This issue occurs because GetMailboxTable and GetMailboxTableOffset do not distinguish between mailboxes from an online mailbox store and mailboxes from a recovery storage group. Therefore, the mailbox table that these methods returns contains all the mailboxes from the particular server. These two methods do not provide a means to filter the returned results to let you determine which mailbox entries are from a recovery storage group.

This hotfix introduces a new interface that is named IExchangeManageStore5. This new interface exposes new functionality to let you retrieve a mailbox table that contains only the mailboxes from a particular mailbox store.

IExchangeManageStore5 contains the following two new methods.

Back to the top

IExchangeManageStore5::GetMailboxTableEx

The GetMailboxTableEx method obtains information about all the mailboxes on a server in a particular store.

HRESULT GetMailboxTableEx(
  LPSTR lpszServerName,   
  LPGUID lpguidMdb,    
  LPMAPITABLE FAR * lppTable,  
  ULONG ulFlags,
  UINT uOffset
);

Parameters

This method supports the following parameters.

Parameter name	Parameter type	Description
lpszServerName	Input	This parameter specifies a string that contains the distinguished name of the server.
lpguidMdb	Input	This parameter specifies a GUID that contains the value of the objectGUID attribute of the information store.
lppTable	Output	This parameter specifies a MAPI IMAPITable interface that contains the information about all the mailboxes on the server that is specified in lpszServerName.
ulFlags	Input	This represents a defined value that specifies whether the server name is in Unicode format. A value of MAPI_UNICODE indicates that the server name is in Unicode format. A value of 0 (zero) indicates that the server name is in ASCII format.
uOffset	Input	This parameter indicates the offset from which to start the table. Use this parameter for stores that contain more than 64K of mailboxes.

IExchangeManageStore5::GetPublicFolderTableEx

The GetPublicFolderTableEx method obtains information about all the public folders on a server in a particular store.

HRESULT GetPublicFolderTableEx(
  LPSTR lpszServerName,   
  LPGUID lpguidMdb,    
  LPMAPITABLE FAR * lppTable,  
  ULONG ulFlags,
  UINT uOffset
);

Parameters

This method supports the following parameters.

Parameter name	Parameter type	Description
lpszServerName	Input	This parameter specifies a string that contains the distinguished name of the server.
lpguidMdb	Input	This parameter specifies a GUID that contains the value of the objectGUID attribute of the information store.
lppTable	Output	This parameter specifies a MAPI IMAPITable interface that contains the information about all the public folders on the server that is specified in lpszServerName.
ulFlags	Input	This represents a defined value that specifies whether the server name is in Unicode format. A value of MAPI_UNICODE indicates that the server name is in Unicode format. A value of 0 (zero) indicates that the server name is in ASCII format.
uOffset	Input	This parameter indicates the offset from which to start the table. Use this parameter for stores that contain more than 64K of public folders.

Hotfix installation information

After you apply this hotfix, you must enable the new interface. To do this, follow these steps.

Step 1: Add the declaration for IExchangeManageStore5 interface to edkmdb.h

Add the following to edkmdb.h.

/*------------------------------------------------------------------------
 *
 *	"IExchangeManageStore5" Interface Declaration
 *
 *	Used for store management functions.
 *
 *-----------------------------------------------------------------------*/

#define EXCHANGE_IEXCHANGEMANAGESTORE5_METHODS(IPURE)					\
	MAPIMETHOD(GetMailboxTableEx)									\
		(THIS_	LPSTR						lpszServerName,				\
				LPGUID						lpguidMdb,					\
				LPMAPITABLE FAR *			lppTable,					\
				ULONG						ulFlags,					\
				UINT						uOffset) IPURE;				\
	MAPIMETHOD(GetPublicFolderTableEx)								\
		(THIS_	LPSTR						lpszServerName,				\
