Users experience an issue where adding members to a Viva Engage community via CSV import triggers a success notification, but the actual member count does not update.

How to Fix Viva Engage CSV Member Upload Completed but Members Missing

Product: Viva Engage
Device & OS: not provided
Scenario: Importing community members using a CSV file in Viva Engage.
Observed behavior: The upload process completes with a success notification, but the imported members are missing and the community member count remains unchanged.

Before you start

Ensure you have the correct administrator privileges in your organization, as escalating this issue may require accessing the Microsoft 365 admin center.

Solution 1Recommended

Verify Member Count in an Incognito Browser Window

Check if the issue is caused by browser cache or session data by viewing the community in a fresh incognito window.

Adding members to a Viva Engage community by importing a CSV file does not require any additional configuration. Since you received a successful-upload notification, the file was likely processed correctly.

To rule out a browser display issue, use an incognito or private browsing window to bypass cached data and view the most recent server state.

Open an incognito window

Launch Google Chrome, click the three-dot menu in the top right corner, and select 'New Incognito Window'.

Access Viva Engage

Navigate to Viva Engage and log in with your credentials.

Check the community

Open the specific community where you uploaded the CSV and check if the member count has now updated.

Wait for sync: Sometimes large CSV files take a few moments to fully sync across the servers, even after a success message is displayed.

Solution 2

Collect HAR Logs and Contact Microsoft Support

If members are still missing after verifying without a cache, the issue requires deeper investigation by Microsoft's development team.

Frequently Asked Questions

Do I need to configure additional settings after a CSV upload in Viva Engage?

No, standard CSV uploads in a Viva Engage community do not require extra settings. Once you receive the success notification, the members should automatically be added.

Why did my CSV upload say successful but no members were added?

This can happen due to browser caching, a delay in server synchronization, or an internal backend error. Checking in an incognito window can rule out caching issues.

Can a non-administrator submit a support ticket for this issue?

No, administrator privileges are required to create a support ticket in the Microsoft 365 admin center. If you are not an administrator, you will need to contact your organization's IT admin to raise the ticket on your behalf.
