How to Sync Mobile Numbers from Active Directory to Microsoft Delve
Question details
The user needs to synchronize mobile phone numbers from an on-premises Active Directory to Microsoft Delve and SharePoint without relying on PowerShell scripts.

- Product
- Microsoft 365 / Active Directory
- Device & OS
- not provided
- Scenario
- Updating employee contact information centrally in Active Directory and ensuring those changes reflect across Microsoft 365 services like Delve.
- Observed behavior
- Profile data must seamlessly map from the identity provider (Azure AD) to the user-profile synchronization services in SharePoint to update the Delve interface.
Ensure you have the necessary administrative privileges in both your on-premises Active Directory and the Microsoft 365 admin center before monitoring or adjusting synchronization settings.
Utilize Azure Active Directory Connect Synchronization
Rely on the built-in Microsoft 365 identity and user-profile synchronization services to automatically push Active Directory updates to Delve.
Microsoft 365 handles profile data through a multi-step synchronization process. On-premises Active Directory changes are first synced to Azure Active Directory (Azure AD), which manages overall identity information. From there, SharePoint Online receives the profile data through dedicated user-profile synchronization timer jobs, which eventually updates Delve.
Open your on-premises Active Directory Users and Computers (ADUC) console and update the 'Mobile' attribute for the targeted user profiles.
Allow Azure AD Connect to run its scheduled delta sync (usually every 30 minutes) to push the updated mobile numbers to Microsoft 365.
Allow time for SharePoint Online's backend user-profile synchronization to pull the updated Azure AD data into the Microsoft Delve environment.
If the synchronization fails after waiting the required period, visit the Microsoft Q&A forum for specific backend or Microsoft Graph troubleshooting.

Streamline Your Document Workflows with WPS Office
While managing Active Directory synchronization requires Microsoft admin tools, your everyday document creation shouldn't be complicated. WPS Office provides a free, lightweight, and highly compatible alternative to Microsoft Office for creating, editing, and sharing organizational documents across all your devices.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation package for your operating system.
- 2. Install the Application: Run the downloaded file and follow the straightforward on-screen instructions to complete the installation in minutes.
- 3. Open and Edit Microsoft Formats: Launch WPS Office and directly open your existing Word, Excel, or PowerPoint files without worrying about formatting issues.

Frequently Asked Questions
Why is the updated mobile number not showing in Microsoft Delve immediately?
Profile synchronization between Azure Active Directory and SharePoint Online (which powers Delve) runs on scheduled background timer jobs. It can take up to 72 hours for changes made in Active Directory to fully propagate and appear in Delve.
Can I update user mobile numbers directly in Delve instead of Active Directory?
If your organization uses Azure AD Connect for identity management, user attributes like mobile numbers should be updated at the source (on-premises AD). Modifying them directly in Delve or Microsoft 365 can result in the changes being overwritten during the next directory sync cycle.
Where can I get support if my Azure AD Connect synchronization is failing?
For advanced backend synchronization issues, PowerShell queries, or Microsoft Graph API troubleshooting, Microsoft recommends posting your logs and specific scenarios on the official Microsoft Q&A forums dedicated to Azure Active Directory.
