Notes on Using Message Store Properties

• New message store properties You cannot create new properties on message store objects. You can, however, create properties on messages, folders, and attachments.
• Message store properties on the profile The PR_DISPLAY_NAME and PR_COMMENT properties are stored in a user’s profile, not on the server. This allows users to assign display names to the information store services in their profiles.
• Values of PR_MDB_PROVIDER This MAPI property contains a provider-defined identifier that indicates the type of the message store. For more information, see Identifying Providers by Provider GUIDs.
• Unsupported Functions on Public Message Stores You cannot call the following MAPI methods to perform actions on public information stores: IMsgStore::SetReceiveFolder, IMsgStore::GetReceiveFolder, IMsgStore::GetReceiveFolderTable, and IMsgStore::AbortSubmit.
• Unicode Not Supported for GetReceiveFolder Calling the MAPI IMsgStore::GetReceiveFolder method with the MAPI_UNICODE flag set causes an error (MAPI_E_BAD_CHARWIDTH) to be returned.
• Notifications Calling the Advise method to request all notifications on the entire public information store is not supported. An Advise method call for all notifications on the private information store refers to all notifications on the mailbox, not for the entire private information store. For more information, see Using Event Notifications.
