In Outlook 2003 I used categories to define the kind of task or appointment and the contacts field to connect the task/appointment to contacts. In Outlook 2007 the contacts field is gone and there is no way to enter a contact (or group of contacts) to a task.
Is there a way to add contacts to tasks/appointments in Outlook 2007?
Contact Linking has been turned into an option which is disabled by default.
You can enable it in the following way
- Outlook 2007
Tools-> Options…-> button Contact Options...-> select: Show Contact Linking on all Forms
- Outlook 2010
File-> Options-> section Contacts-> select: Show contacts linked to the current item
Enabling Contact Linking in Outlook 2010.
Outlook 2013 and Outlook 2016 Registry key
In Outlook 2013 and later, the interface option has been removed and support for Contact Linking can only be enabled via a Registry key.
