headers means that spf-tools-perl gets called by exim4. What I suggest to debug this is to manually call spfquery.mail-spf-per with the relevant parameters (see the spfquery.mail-spf-perl manpage), and check if what kind of reply you get for your incoming outlook mail. The tool's help screen (spfquery.mail-spf-perl --help) has examples on how to invoke it.
