How do i move the left sidebar on mac mail

By default, the left sidebar in Mac Mail is fixed and cannot be moved. However, you can resize the sidebar by dragging the separator line between the sidebar and the main mail window. Here's how:

1. Open Mac Mail on your Mac.
2. Click and hold on the separator line between the sidebar and the main mail window. You'll see a small handle appear.
3. Drag the handle to the left to make the sidebar narrower, or to the right to make it wider.
4. Release the handle when you've reached the desired width.

Note that you can't move the sidebar to a different location on the screen, only resize it. If you want to hide the sidebar altogether, you can do so by clicking on the "View" menu and selecting "Hide Sidebar" (or use the keyboard shortcut Command + Shift + S).
