Question

What does limited access to a document mean?

Answer 1

Limited access to a document usually means that the creator of the document is able to limit how much access one person is able to get.

Answer 2

A user who has limited access is not able to change permissions to a document to which they should have full control of. It enables the user read the document but not edit it. One way to limit access to a document is to restrict editing permissions before you send the document to other people. This will prevent them from editing and confidential information.
