\begin{document} implicitly means begin typesetting. However, by doing
your \input in the preamble some things may not have been set up yet
for typesetting (as you intend it) to happen. The microtype package
does many, many things behind the scenes so I'd wait with all such
things to _after_ \begin{document}.
