Contact Unification across Outlook and Teams

Contact Unification across Outlook and Teams

Teams and Outlook contacts will be unified by August 2025, allowing changes in one to reflect in the other. Migration began in January 2024, with a full unified experience rolling out from December 2024. Users may see duplicate contacts labeled ‘Teams Conflict’ during transition. Update training and documentation accordingly. Updated July 31, 2025: We have updated the timeline. Thank you for your patience. Today, users can see Outlook contacts created with their Entra ID (AAD) account in Teams, but contacts created in Teams are not available in Outlook. To provide a consistent experience we are making changes to allow Teams contacts, created with a user’s Entra ID (AAD) account, to be visible in Outlook as well. Upcoming changes to contacts in Teams and Outlook: Currently, Teams and Outlook maintain separate contact lists for enterprise users. Based on your feedback, we plan to introduce a unified contact experience, ensuring a consistent contacts experience across Outlook and Teams. In future, changes to contacts in users’ organization (Entra ID) account in Teams will reflect in Outlook and vice versa.  What’s Happened so far:  We have completed one round of migration of all Teams contacts to Outlook in January 2024.  As a result, users may see more contacts in Outlook, namely those created in Teams and potentially Skype for Business contacts (if enabled).  Existing Outlook contacts may also be enriched with additional details from corresponding Teams contacts.  Teams users can see Outlook contacts but cannot edit them inside Teams.  What’s Coming:  Users will gradually upgrade to the new unified experience from December 2024. The new experience will be enabled for each user across all endpoints (Desktop, Mobile, Devices etc.) simultaneously. Once the new experience is enabled for a user, they will see same set of contacts in Outlook and Teams. Any change in Outlook will reflect in Teams and vice versa.  When this will happen: This activity is expected to be completed for all active users by August 2025 tentatively (previously June). Once this activity is complete, users will work with a single contact list across Teams and Outlook.  How this will affect your organization […]
