  • By default, the administrator has the permission to edit the SMTP proxy addresses. You can also grant the permission to a user.

    Here’s a similar situation as yours:

    Ensure the user has the proper permission and try again.

  • Are you using Exchange 2003?
    Did you connect remotely using ADUC on a workstation in a remote network segment to modify SMTP proxy addresses?

    This problem can occur if there is an access list on a network router in between the network segment that the workstation belongs to and the Exchange server's network segment that did not include the IP address of this workstation; in this case, once that access list was removed, the problem was resolved.

    If your enviroment doesn't like this, please provide us with more details.

  • It is not from PC's mmc snapin . It is done from ADUC of  a DC by using remote desktop from PC to that DC.

    Usually we use domain admin to change proxyaddresses, but it needs approval to use domain admin.

    So I would like to do it by daily operation account so, I would like to know how to do it.

  • You can refer below article or you can use GUI way to delegate the permission require to change proxyaddress attribute. The user/group delegated requires read/write access to this attribute.
