It’s easy to share contacts with your team.
What is contacts sharing?
When you use Microsoft Outlook with a Hosted Exchange, your contacts can be shared between people in your domain. Contact sharing is not limited to the default Contacts folder that is created in all Outlook profiles. You can create additional contacts folders and choose which of those folders to share. For example, you can create a contacts folder for a specific project and share it with co-workers within that project. Optionally, you can grant them permission to modify the contacts.
works through sharing invitation and sharing request e-mail messages. Sharing invitations offer the recipient access to your contacts folder. When you send a sharing invitation for your default Contacts folder, you can request access to the recipient’s default Contacts folder.
