Access Denied Error in SharePoint List Board View During Drag-and-Drop for some users

Hi dharam2​ 

Pl refer some workaround which might help

1.Switch from “Contribute” to “Edit” Permission Temporarily

• In some cases, Contribute permission may not be sufficient for Board View drag-and-drop, especially if:
• The field being updated has workflow triggers
• Or if it's connected to Power Automate/Flows

Try giving an affected user Edit permission temporarily and retest.

2.Disable and Recreate the Board View

• A corrupted or partially cached view can cause this:
• Delete and re-create the Board view using the same field.
• Do not clone or reuse the old view via Save As.

3.Force Refresh Permissions via PowerShell (if inherited)

Sometimes inheritance looks intact but is not. You can reassert it via PowerShell:

# Force re-inherit permissions for all items

Get-PnPListItem -List "Your List Name" | ForEach-Object {

    Set-PnPListItemPermission -List "Your List Name" -Identity $_.Id -InheritPermissions

}

Backup first and test on a subset!

4.Use Classic Grid View for Updates (Temporarily)

If business critical, advise users to use Grid View (Quick Edit) until Microsoft resolves the Board View issue.

5.Raise Microsoft Support Ticket

This is increasingly being reported on:

• Microsoft 365 forums
• Admin center messages (some tenants are seeing advisories)

If you're a Microsoft 365 admin, check Health Center or raise a ticket. This may be a rolling update bug.
