In Lotus Notes 8.5.3, I used to be able to put a check mark on multiple messages if I wanted to move or delete them.
How do I add this column back to the far left of my inbox?
Select "Preferences" from the File menu.
Click on "Basic Notes Client Configuration" in the left-hand pane.
Scroll the slider in the "Additional Options" box down to the bottom.
Click on "Show check marks in margin for selected documents".
You might have quit and restart your Notes client for this to take effect.
