This hotfix adds a new method that is named GetPublicFolderTableOffset. You can use this new method in the new IExchangeManageStore4 interface. The original GetPublicFolderTable method and the original IExchangeManageStore3 interface are still available. Both the GetPublicFolderTableOffset method and the GetPublicFolderTable method now return a full (65,536 row [64K row]) MAPI table even if there are more than 65,536 rows to be returned. The new GetPublicFolderTableOffset method contains an additional argument that is named uOffset. You can use the uOffset argument to start retrieving data from a specific place in the master table. The uOffset = 0u argument directs this method to start at the beginning of the table. For example, you can programmatically make the following calls until an empty table is returned: For additional information about the terminology that is used to describe Microsoft product updates, click the following article number to view the article in the Microsoft Knowledge Base:
