Are you able to produce a much smaller file that shows the same bug, that we could use for unit tests etc? We try to avoid large files in the test suite where possible

From a quick look at the file supplied, it seems to be much the same as a normal outlook file, with an additional smime.p7m attachment. (Plus a few unknown + unsupported chunks)

ZIP Attachment with Outlook E-Mail with and without signature

case signed:  only one chunk by msg.getAttachmentFiles()

case unsigned:  two chunks:  pdf and word file

Perhaps its a bug in the Apache Tika class org.apache.tika.parser.microsoft.OutlookExtractor

sorry, edit for last comment:

case with signature:    only one chunk by msg.getAttachmentFiles()

case without signature: two chunks:  pdf and word file
