Where Microsoft Exchange Server keeps its logs

Microsoft Exchange Server logs to %ExchangeInstallPath%TransportRoles\Logs\MessageTracking\ on Windows. 3 other Windows log locations are recorded below.

Paths are printed exactly as Microsoft Exchange Server writes them. Environment variables like %LOCALAPPDATA% and $XDG_STATE_HOME are never expanded, so a path can be pasted straight into a shell. Where a path differs between installer types or shipping flavours, each one is racked as its own card below - why that happens.
