Microsoft Outlook

Where Microsoft Outlook keeps its logs

Microsoft Outlook logs to %TEMP%\Outlook Logging\ on Windows.

Microsoft Outlook logs to ~/Library/Containers/com.microsoft.Outlook/Data/Library/Logs/ on macOS.

Paths are printed exactly as Microsoft Outlook 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.
