Do you want to two-way sync contacts back and forth between your two Microsoft 365 mailboxes? Or perhaps you want to sync contacts across all users from a single shared contact list? If so, you’ve come to the right place! In this article, we’ll demonstrate how to use the CiraHub platform to quickly and effectively start two-way syncing all of your contact information.

This article will outline how to two-way sync contacts between Microsoft 365 User Mailboxes within the same organization.

Two-Way Contact Sync Between Microsoft 365 User Mailboxes

  1.  First, Log in to CiraHub. You will be taken to the onboarding wizard. (See figure below.) Next, select the object you want to sync. In this example, the contacts object has been selected

Contact and Calendar Selection

2. Next, start the Hub and Spoke setup. Click on Microsoft 365 in my tenant as your source type for your contact spoke. (The Hub contains all synced Contacts from each spoke; a spoke can be a Public Folder, a user mailbox, the GAL, or a CRM.) 

 

Select Source Type of your contact spoke

3.   Select User Mailbox as the contact spoke type.  

  Select “User Mailbox” as the contact spoke type.  

4. Choose a User Mailbox to two-way sync User Mailbox contacts. You will have to scan through your global address list and select the user’s Mailbox Folder you would like to sync.

Choose a User Mailbox to use as the sync source.

5. Next, type in the “Spoke Name” that users would like to use and click Create to two-way sync Microsoft 365 User Mailboxes. It is important to name and label your spoke so you can efficiently sort through and find it.

6. Now, if you wish to add an additional mailbox to this contact hub, please reference steps 2 – 6.

7. Next, right-click your spoke, and select “Sync Options”.

Next, right click your spoke, and select “Sync Options".

8 Click Allow Hub to create and sync items in this spoke. This will enable you to two-way sync contacts between Microsoft 365 Mailboxes from the endpoint to the hub database and back. 

  Click on “Allow Hub” to create and sync items in this spoke.

9. Repeat this process with any number of mailboxes you wish to keep in sync. Once that is complete, click “Sync Now” to begin the syncing process, from here on out until disabled, the two contact sources will stay continuously updated with one another.

Repeat this process with any number of mailboxes
