Outlook 2007 Error "An Internal Support Function Returned an Error" when trying to send an email.

    Question

  • I have a user who is trying to send an email to a group from his contacts in Outlook 2007.  He receives the following error "an internal support function returned an error".  This is a group that he frequently emails.  Thanks.

  • Hi mardner,

    Based on my research, this error might caused by that there is a duplicate, one-off contact in the DL, containing the Internet address for a member of the Microsoft Exchange Server Global Address List (GAL).

    To workaround this:

    a, Do not use the identical display name for one-off contacts in a DL that also have Internet entries in the GAL.

    b, If you need to include a GAL member's Internet address in a contact DL, use a different display name.

     

    PS: A one-off address entry is made in a DL by clicking the Add New button and then adding the recipient and Internet e-mail address without adding the recipient as a contact.
