Can I share a contacts folder with other people from Outlook Web App?

The feature to share or view a shared contacts folder is not supported in Outlook Web App. If you want to share contacts with people inside or outside your organization, we recommend that you use the share contacts feature in Outlook 2013. For information, see Share a contacts folder with others. Another way you can share contacts with people inside your organization is by using a shared mailbox. A shared mailbox is something that can only be created by an admin in your organization. With a shared mailbox , users that have permission to the shared mailbox can access a shared mailbox, calendar, and contacts.
