To share your contacts
In People, in the Folder Pane, select the contact folder that you want to share with a person in your organisation.
Select Home. Then, in the Share group, select Share Contacts.
In the To box, enter the name of the recipient for the sharing invitation message. If you want to, you can change the Subject.
If you want to, request permission to view the recipient's default People folder. To do so, select the Request permission to view recipient's Contacts folder check box.
In the message body, type any information that you want to include, and then select Send. Review the confirmation dialog box, and then if correct, select OK.
The person in your organisation receives the sharing invitation in email, and select Open this Contacts folder.
