CiraSync Contact Lists can use Collections as a source or a target: this provides flexibility to add or remove users or contacts using an existing group in the Global Address List. CiraSync Contact Collections can be created from a Group, a Distribution List, and a Dynamic Distribution Group created on a single Azure Active Directory Premium Subscription.

This guide shows how to set up Azure Active Directory Premium, create Dynamic Distribution Groups, and how to use the group as a source to create Contact Collections.

NOTE: Due to recent changes done by Microsoft, updates done to Dynamic Distribution Lists in Office 365 will take up to 24 hours to show in the respective DDL (Dynamic Distribution List). Because of this, updates done by the Scheduled run in CiraSync might take up to 48 hours to show. A manual sync from the Dashboard, after the update shows in the DDL, will propagate the change faster.

Create Contact Collections from Office 365 Distribution Groups

1. Log in to the CiraSync Enterprise Edition Dashboard.
2. Click the + in the Contact Collections (See figure below.) You will be taken to the Contact Collection Dashboard. (See figure below.)
3. Click the Pen icon.
4. Name the Collection.
5. Search for the Distribution Group you created earlier in the Creating a Distribution Group section of this guide.
6. Click the group. The group should appear in Collection Preview on the right.
7. Click SAVE at the top-right corner of the dashboard.

Now that you’ve created Dynamic Distribution groups, let’s view the Global Address List through Outlook.
