The only way I know how to do this is using a macro. Open the document and press ALT + F11 to open the VBA editor. In the project explorer window on the left you will need to right click the object labeled "ThisDocument" and choose "View Code"
Paste the code below into the blank code window and save the document. You will need to adjust the macro security level to medium or low from the main Word window by clicking
TOOLS --> MACRO --> SECURITY Code:
Private Sub Document_Open()Selection.EndKey Unit:=wdStoryEnd Sub
You can also accomplish the same action without using a macro by opening the document and clicking
CTRL + END to take you to the last page.
