Send on behalf problem, after restoring backup to another exchange RRS feed

  • Question

  • Hello,

    We are facing this problem: After restoring mailbox items from a backup of a Windows Small Business Server 2003, to a new Exchange 2010 on a new domain (but same mail configuration), users cannot update calendar objects created into SBS 2003 and send this modification to participants. When users try to do this (or delete a meeting), they receive the following error: 

    "No puede enviar un mensaje en nombre de otro remitente a menos que tenga permiso para ello. Asegúrese de que está enviando el mensaje en nombre del remitente correcto o solicite el permiso necesario. Si el problema continúa, póngase en contacto con el departamento de soporte técnico."

    Similar error message i found on internet: 

    "You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk."

    Difference: spanish message does not say "... on behalf of this user", but "... on behalf of another user".

    The problem is that users are not trying to do that. They just want to update a meeting and resend the meeting update to all participants. The calendar objects with problems are thoose that has been created on the old exchange 2003. 

    Aditional information:

    - users mailbox alias and address are the same in old and new exchange

    - migration of data was made with ARCServe Backup r16.5, with brick level backup (backup of the individual mailboxes rater than whole database)

    - Domain of the new exchange are a new domain, totally separated of SBS 2003.

    - We do not have this problem whith new calendar objects, made on the new exchange directly.

  • We where able to solve this problem. Seems that exchange 2010 need the legacyExchangeDN attribute of the old domian. So we get theese attribute from adsiedit in the old SBS2003 and go to EMS, open the properties of a user´s mailbox and add a custom x500 address type with the legacyExchangeDN attribute from the old exchange.


    - Do not edit attributes with adsiedit on new domain.

    - Check that after you add the custom x500 address, you will be able to see it with adsiedit on new domain, in the proxyAddress attribute of the user object.
