A plane charge would be an infinite 2-dimensional sheet with constant charge density. Already in a line charge you have neglected edge effects, because the $1/r$ dependence holds true only near the line provided you are far away from the end-points. Similarly, for a plane, the constant electric field holds true provided that you are much closer to the plane than you are to it's edges. You make this approximation when you derive the electric field inside a parallel plate capacitor, for example. If you truly could assemble an infinite sheet of charge, conservation of energy would be the least of your worries. Good luck with the SAT.

Do electric fields generated by plane charges lose intensity over distance? If not, why?
Recently I created/removed some folders on Outlook desktop app.

When I synchronized my corporate account by manually refreshing under the folders screen, it didn't bring the new folders, nor removed the removed ones.

Is this a known bug?

I have a Motorola Milestone, and I remember in the past, at least the folder addition worked.
