I saw the message "Downloading Messages Paused (On Battery)" in Mail.app in El Capitan.
What does this mean? The MacBook was plugged in to the wall, not running on battery. What would cause downloading to stop/pause?
MacOS – “Paused (On Battery)” mean in Mail.app

Generally this message is displayed by Mail.app in OS X El Capitan, when MacBook is running on battery power and is low on charge. As your MacBook is connected to power, first try clicking the reload button shown alongside, Paused (On Battery) text. If that doesn't work, try relaunching Mail.app to see if that resolves the issue.
