Hi, There are 300 Mailboxes, i want to disable MAPI for all these mailboxes. thanks

Have you checked the properties of a mailbox in tha OU, it seems like that the command has worked (before) oand nothinghas changed, i.e check John MAPI setting and see if this has already been disabled. Sukh

Hi, >WARNING: The command completed successfully but no settings of 'contoso.com/sales/john' have been modified. This generally means the values were already what you tried to set them to - so no changes were necessary. Check the john's mailbox setting if MAPI has been disabled.
