Use this interactive demo to learn how to identify and remove duplicate records in your Dynamics 365 environment.

‍

To find duplicates in Dynamics 365, you must modify your settings. Here’s how:

‍

Access settings by clicking the gear icon.
Select 'Advanced Settings'.
Navigate to the 'Data Management' from your side bar menu.
Then, select 'Duplicate detection settings'.
Ensure 'Enable duplicate detection' is enabled.
Make sure that each box is checked.
Click 'Saved' to confirm the action.

📌 Why this matters

Finding duplicates prevents data pollution that silently undermines your sales and marketing efforts. When duplicate contacts exist, you'll send multiple emails to the same person, skew your analytics, and create confusion about customer interactions across your team.

Beyond the obvious cleanup benefits, enabling duplicate detection acts as a gatekeeper for future data imports and manual entries. This means your CRM stays clean automatically rather than requiring periodic manual audits, saving hours of detective work later when trying to merge conflicting customer records.
