Fix SharePoint Not Sending Emails to One Specific User
Question details
A single user is not receiving SharePoint notification emails despite having correct permissions, likely due to an outdated email address cached in their SharePoint user profile.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- An administrator is attempting to restore missing SharePoint email notifications, such as file-sharing alerts, for a specific user account.
- Observed behavior
- SharePoint notification emails fail to reach one specific user, even though their Exchange settings are correct and messages sent directly to their alias arrive successfully.
Verify with the affected user whether they are missing all types of SharePoint emails (like file-sharing notifications and site alerts) and ask them to check their Junk or Spam folders to rule out local email filtering.
Verify and Update the SharePoint User Profile
Resolve email mismatches between Microsoft Entra ID (Azure AD) and the SharePoint Admin Center to ensure notifications are routed to the correct address.
SharePoint maintains its own user profile directory that syncs with Azure AD. If a user's primary email address changes, the SharePoint profile may retain the old address, causing email notifications to fail.
Sign in to the Azure portal, navigate to Microsoft Entra ID > Users, and search for the affected user to verify their 'User Principal Name' and 'Email' properties match.
Log in to the SharePoint Admin Center, click on 'More features' in the left navigation pane, and select 'Open' under 'User profiles'.
Click on 'Manage user profiles' and use the search bar to find the affected user's profile.
Edit the user's profile and ensure the 'Work email' field exactly matches the primary email address listed in Azure AD. Save the changes.
Remove and Re-grant Site Permissions
If the user profile is correct but emails still fail for a specific site, refreshing the user's permissions can force the site to recognize the updated profile.
Check Personal SharePoint Notification Settings
Ensure the user has not accidentally disabled their personal SharePoint email notification preferences.

Frequently Asked Questions
Why does a user's SharePoint profile have an old email address?
SharePoint user profiles are synchronized from Azure Active Directory. If a user's primary email was recently changed or an alias was assigned, but the automatic sync process failed or was delayed, SharePoint may retain the outdated email address, preventing notifications from routing properly.
Can I manually force a sync between Azure AD and SharePoint?
While automatic synchronization occurs continuously in the background, delays can happen. Administrators can manually update the email property in the SharePoint admin center under 'Manage user profiles' to immediately correct a mismatch without waiting for the sync.
Are SharePoint email alerts specific to individual sites?
Yes, alert settings are typically configured per site or per document library. If a user is missing emails from only one specific site, the issue is likely tied to their local permissions or custom alert settings on that particular site rather than a global profile issue.
What if the email settings are correct but messages still aren't arriving?
Ask the user to thoroughly check their Junk or Spam folders. If the emails aren't there, a Microsoft 365 administrator should review the Exchange message trace logs to see if the outgoing SharePoint emails are being blocked by spam filters, malware policies, or mail flow rules.
