I am using outlook 2003 off an exchange 2003 server. I am logged in as admin and can send an email to a distribution list ok from a shared contacts entry. The user can select the same entry but gets "an internal support funtion returned an error" when they try send. The have ownership rights to the shared contacts. When they try expand out the distribution list from within the email they get error cannot perform requested operation the command selected is not valid for this recipient. could not complete the operation. one or more parameter values are not valid.
I checked all the address and they look fine. any ideas
