We are using Outlook 2007 on an Enterprise Server. I have a shared calendar for scheduling volunteers that many people across the organization access. Due to situations where an employee may need to contact a scheduled volunteer, I want to link the appointments to their contacts. I know how to insert the contact item into the appointment. However, I collect other personal information on volunteers that I don't need everyone in the organization to see. I want them to only have access to their phone number. Therefore, I want to create a custom form that only displays that information. The trick is figuring out how to set it up so when the employee clicks on the contact item in the appointment, it opens to the custom form no matter what user/employee clicks on it. Is there a way to make this happen across the organization?? Thanks!
