Hello,
Thank you for posting in Q&A forum.
Based on your description, there are a few steps you can take to try to resolve or further diagnose the issue:
- Check User Profile Sync: Make sure the User Profile Service Application (UPA) in SharePoint is syncing correctly with Active Directory. Sometimes there can be delays or issues with the sync process that prevent updated information from flowing from AD to SharePoint.
- Clear SharePoint Profile Cache: Sometimes old information is displayed because it is cached. Clearing the User Profile Service Application cache in SharePoint may help update the displayed information.
- Microsoft Graph API: Verify that the information retrieved through the People Web Part matches the information seen through the Microsoft Graph API query. You may need the assistance of a global administrator to do this. Comparing the results can help determine if the problem is on the API side, SharePoint side, or AD side.
- Profile Update in Delve: Ask the affected users to manually update their profile information directly through Delve (part of Office 365). Manual updates in Delve may help push the correct information to other services.
- Outlook and Teams cache: Because this issue affects email, it may also be associated with contact data being cached in Outlook or Teams. Clearing the local cache for these applications may help. For Outlook, you can clear the cache through the local user profile settings. For Teams, sign out and then sign back in to refresh the cache.
I hope the information above is helpful.
Best Regards,
Yanhong Liu
