In Microsoft Outlook, it is easy to share Contacts in a mailbox; however, it is not so easy to share that contact folder with smartphones. With CiraSync Enterprise Edition, you can sync Contacts and Calendars from a User/Shared Mailbox to any number of users in your Office 365 tenant.

This guide shows how CiraSync Enterprise Edition can sync Microsoft Exchange mailboxes to an entire Office 365 Tenant!

Before You Start

This guide assumes that a dedicated Service Account with Application Consent Access has been set for your Office 365 Tenant. Without an administrator account with the appropriate settings configured, CiraSync will be unable to push Contacts and Calendars updates to user mailboxes. Check out the following articles to learn how to set up a dedicated Service Account with the appropriate permissions for your Tenant and then return here to learn how to sync User/Shared Mailboxes with CiraSync Enterprise Edition:

1. Setting up a Dedicated Service Account for CiraSync in Office 365

3. Making CiraSync Use a Specific Office 365 Service Account

This guide also assumes that a Collection was created as a Target prior to creating a Contact List. Check out the following article to learn how to set up Collections:
