After Providing send as permission for distribution groups which are migrated to different Domain , Unable to send mails from the distribution group.

    Question

  • Dears 

    We have migrated our current Exchange 2013 CU11 from "x.com" to "y.com" .

    After the Migration which is again exchange 2013 , when we are providing send as permission to any distribution group for a user and then when trying to send a mail from the user's mailbox , the following error occurs .

    "you do not have the permission to send the message on behalf of the specified user"

    I have provided send as permission from both the "Exchange Admin Center" and from the AD .

    Still the same error. When I try to add the user from "Account Settings" in the outlook under advanced in "More settings" then the following error occurs .

    "The name cannot be resolved , the name cannot be matched to a name in the address list "

    Similarly when I try adding the user using the "Delegate  Access" permission in the outlook , the following error occurs.

    "The user cannot be , non-local users cannot be given rights on this server"

    From the above error I can understand that the users are fetched from the new domain "y.com"however we have a trust relationship enabled between both the domains in AD. 

    Kindly give all your insights on the above scenario.

  • Hi Joyso,

    Welcome to Technet forum.

    Could you tell us more details about this issue? For example:

    Which domain DG belong to?

    Which domain user belong to?

    If there are different domains, we should create a mail contact on x.com and add user who is in y.com, then add send on behalf permission to mail contact. We could refer to the following link:

  • Hi Joyso,

    This affecting all users inside the distribution group? Can you try to run the below command for one of the user then add the delegate again?

    Set-Mailbox -identity UserA -type Room

    Then immediately run

    Set-Mailbox -identity UserA -type Regular
