Scenario. You have connected your SharePoint Online lists to your Access database and you are trying to update some data via Access. You get the following error “Data cannot be Added, Updated or Delete because UserInfo has not been fetched from the server.” And when you open UserInfo you get a bunch of deleted text where data should be in fields.
1. Go to File->Options
2. Click on “Current Database” in the Access Options.
3. Uncheck everything under “Caching Web Service and SharePoint tables”
You should be able to view UserInfo now and then be able to update your data from Access.
