Question details

The user needs to resolve an issue where the SharePoint Migration Tool stops at 19% due to an Azure queue acquisition failure.

Product: SharePoint Migration Tool
Device & OS: not provided
Scenario: Running a data migration to SharePoint with custom Azure Storage enabled.
Observed behavior: The migration process halts at 19% and displays the message 'Package Engine has stopped because acquiring Azure queue failed' along with ErrorCode: 0x02040015.

Before you start

Ensure you have global administrator or SharePoint administrator privileges and access to the Azure portal to verify your storage account settings.

Solution 1Recommended

Verify Azure Storage Configuration and Network Rules

Check if the SharePoint Migration Tool has the correct credentials and network access to your custom Azure Storage.

This error generally occurs when the migration tool is unable to authenticate or reach the Azure queue due to incorrect keys or strict firewall rules.

Access Storage Account

Verify Access Keys

Click on 'Access keys' in the left menu and confirm the connection strings are correct and currently active.

Check IAM Permissions

Go to 'Access Control (IAM)' to ensure your migration account has the necessary queue access permissions, such as the Storage Queue Data Contributor role.

Adjust Firewall Settings

Select 'Networking' and adjust your firewall settings to allow the SharePoint Migration Tool's IP addresses to reach the storage account.

Solution 2

Temporarily Disable Custom Azure Storage

Bypassing the custom Azure Storage option allows the migration to continue using Microsoft's default provisioning.

Solution 3

Submit a Support Request with Migration Logs

If the error persists despite correct configurations, Microsoft Support can analyze the migration logs to pinpoint the underlying queue acquisition failure.

Frequently Asked Questions

What does ErrorCode 0x02040015 mean in the SharePoint Migration Tool?

It indicates that the Package Engine stopped because it failed to acquire the Azure queue. This usually points to misconfigured custom Azure Storage, incorrect access keys, missing permissions, or network firewall blocks.

Can I resume my migration after fixing the Azure Storage settings?

Yes, once you correct the permissions or firewall rules in the Azure portal, you can safely resume the SharePoint Migration Tool task from where it paused (typically around 19%).

Where do I find the SPMT error logs?
