Microsoft 365 Not Syncing Contacts

This article will provide a walkthrough on troubleshooting Microsoft 365 when contacts are not syncing.

Check the Setup

Ensure you've properly followed one of the guides below to setup the contact synchronization. Once they've been setup, give it at least 2 hours to synchronize the first time before proceeding with troubleshooting.

• Sync User Contacts
• Sync Company Contacts

No Company Contacts Synchronize

Ensure the following questions are true:

• Is the selected account a Shared Mailbox?
• Are the contacts stored in a "Well Known Folder"?
• Are the contacts stored in the root of the folder, and not any subfolder?

If any of the above answers are "No", then you need to correct that for this to work properly

Using Hybrid?

Usually this issue is caused by the Microsoft mailbox being on a dedicated Microsoft Exchange Server and is not a valid Office 365 mailbox. 

To resolve this issue, you will need to get a valid Office 365 mailbox by submitting a request to your Exchange or Global administrator to migrate the mailbox account.
