I'm having the exact same issue!

My problem is that I've got round the exit code issue by this:

ROBOCOPY D:\filetocopy E:\filetocopyto ^& IF %ERRORLEVEL% LEQ 1 exit 0 /MAXAGE:1

The problem which I'm having now is that the '/MAXAGE:1' part of the syntax is being ignored when ran, this is important part of the syntax for me but I also need Robocopy to exit with a code 0 when successful! What am I missing?
