I found this article .. http://community.landesk.com/support/message/14816#14816
I am also experiencing some oddness with the Change Management reminders, in my Incident process I am able to select any user to send a notification too, even one that isnt involved in the process (e.g. a random contact from our database) as long as I select the "Notify Asignee" checkbox on the reminder window.
However ... in Change Management this doesnt appear to be possible, I have checked the notification tables and I can see that the messages are getting there and also the messages are getting into the tps_user_message table but ITBM is not populating the email address from the value type user that I have specified so nothing gets sent.
Is this because in Change you can only explicity use the Raise User (Originator) value and Current Assignment (Asignee) as apposed to a user that you specify??
I have tried unticking the "Notify asignee" checkboxs and just using the user drop down but that doesnt appear to work either ....
any advice appreciated
