Any changes made to list data in either Microsoft Access or using Data Sheet Mode in Internet Explorer are permanent and cannot be restored.
If you make changes to list items using either method, they cannot be restored to a previous version of the list item using version history (if version history has been enabled on the list).
If you delete list items using either method, they cannot be restored from the Recycle Bin in ShareVision.
Please contact Support if you have any questions prior to making any changes to list data using a connection to Microsoft Access or Data Sheet Mode in Internet Explorer.
