Share Contacts Folders with specific people in your organization
The default Contacts folder in Outlook is created in each Outlook profile. This folder can’t be renamed or deleted. You might have additional contact folders. You can share any of these folders by doing the following:
In People, in the folder pane, click the contact folder that you want to share with a person in your organization.
Click Home. Then, in the Share group, click 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. Note: If you want to request access to a contacts folder other than the recipient’s default People folder, you must send an email message that asks for permissions to that particular folder. This option only requests access to the recipient’s default People folder.
In the message body, type any information that you want to include, and then click Send. Review the confirmation dialog box, and then if correct, click OK.
The person in your organization receives the sharing invitation in email, and clicks Open this Contacts folder.
Open a shared calendar in Outlook 2016 (only for Office 365 users on Monthly Channel)
