Hi Deepak Namdeo,

Welcome to Microsoft Q&A Forum!

Having a good day and I hope you doing well!

Thank you very much for sharing the details of the issue you’re experiencing with applying a Retention Label to your SharePoint Online library. I completely understand how disruptive and frustrating it can be when a process that previously worked smoothly suddenly encounters unexpected technical issues.

Based on my research, it appears that this situation is currently affecting a number of other users as well, so you are certainly not alone. There are ongoing discussions in the technical community about this specific problem, and it seems to be related to recent changes on Microsoft’s side. While there is no official confirmation from Microsoft yet, the pattern suggests this could be a system-related issue.

To help you move forward as quickly as possible, I recommend the following steps:

1. Check Service Health in Microsoft Admin Center: Please log in to your Microsoft 365 Admin Center.

In the left menu, select Health > Service health.

2. Raise a Support Ticket with Microsoft: If you do not see any relevant incidents listed, I strongly encourage you to create a support ticket directly in the Admin Center for the fastest and most effective assistance.

Go to Help & support > Contact support.
Describe your issue in detail, for example: “Unable to apply Retention Label to SharePoint Online library. The error returned is: Value cannot be null. Parameter name: Empty correlation Guid.”
Attach any relevant screenshots or error messages to help Microsoft’s support team understand the problem more quickly.

3. Monitor Community Discussions: You may also want to keep an eye on the Microsoft Tech Community forums, where other users and Microsoft experts are sharing updates and potential workarounds for this issue.

Hi Deepak Namdeo,

Thank you so much for your update and for letting me know that you are now able to apply the Retention Label using the CSOM utility. More than anyone, I am truly happy to hear that you have been able to resolve the issue and that your operations are back to normal.

Based on my observations and experience, this issue may be related to some recent changes from Microsoft affecting the SharePoint Online environment. Specifically, the error “Value cannot be null. Parameter name: Empty correlation Guid” often occurs when one or more parameters passed to the SetListComplianceTag method (such as the correlation Guid) are missing or invalid. Additionally, it is possible that recent updates or policy changes in SharePoint Online temporarily affected how these parameters are handled. After the system was updated or after verifying and ensuring all required parameters were provided correctly, the utility was able to function normally again.

If you have no further questions, I will proceed to close this ticket.

If my initial answer helped point you in the right direction, you’re more than welcome to mark it as the “Accepted Answer”. This can make it easier for others facing a similar issue to find their way to a solution as well. Once again, thank you so much for your cooperation and patience throughout this process. If you need any further assistance in the future, please don’t hesitate to reach out to me. More than anyone, I am truly glad that you were able to resolve the issue and resume your normal operations.
