Hi Gail,
The “Retrieve” is: When Access requests list items from a SharePoint list. Linking list to database will also ask Access to retrieve list items from SharePoint list.
That’s why I suspect this may also be the possible cause of the error message. Therefore, I suggest you try to change the registry with the steps in this article.
In the meantime, you can also create a new test list with 2 or 3 items to see if the issue is related to the specific list. You can copy the database file to your local PC folder to check if the issue is related to the server environment.
Thanks,
Rena
