# Why does Salesforce for Outlook (Retiring) create duplicate contacts in Salesforce and Microsoft® Outlook®?

If you sync your team's records and they include different information for some of the same contacts you own, Salesforce for Outlook can create duplicate contacts in both Salesforce and Outlook.

Important Full product retirement for Salesforce for Outlook is scheduled on January 30, 2027. See [Salesforce for Outlook Retirement](https://help.salesforce.com/s/articleView?id=000393445&type=1&mode=1&language=en_US). To keep integrating Microsoft Outlook with Salesforce, check out our next-generation products: the Outlook integration and Einstein Activity Capture. See [Move from Salesforce for Outlook (Retiring) to the Next-Generation Products](https://help.salesforce.com/articleView?id=outlookcrm_sfo_move_parent.htm&language=en_US).

For example, you and a team member both have a contact for Christina Wills. But the two contacts list different companies for her. Salesforce for Outlook syncs the contacts for you and your team members, resulting in duplicates in Salesforce and Outlook.

To avoid this issue, coordinate with your team members so you share the same contact information. You need to remove the contacts containing the outdated information.
