Windows Live Essentials – Adding or Deleting Folders no longer needed

I would like to change my Windows Live Email folder and subfolder organization by adding some new ones and deleting others no longer needed.  Please provide any info or warnings about doing this while on line with my Live Email open for use/modifications.  I am running Live using Windows 7.  Is it simple enough to complete add or delete folder actions on my primary computer, then open my account later using the computer I used to make the changes and/or others, like a Tablet, that also is configured with Windows Live Essentials and that would now show the new folder configuration after all actions are completed?? Thanks for helping :)
