Hi Lavdeep Kumar,
Sorry for the inconvenience caused by this.
Based on my research, this error happens because the edits are blocked and Power Query can change the queries in these connections. I would like to suggest you try this way to check the result:
- Open the Data tab in the Excel window.
- Click on Connections in Toolbar
- You should see connections which you want to delete. Choose them and try to delete.
If the issue persists, we would like to connect more information about it:
- Does this issue happen to newly created worksheet?
- Can you please provide the full screenshot of Excel-> File-> Account-> Product Information for us?
Regards,
Ivy
