Nick Burch commented on TIKA-1092:
----------------------------------

I'm not sure that your problem file is actually a word document. The exception you're seeing is triggered by POI trying to open the file, but discovering that it's not actually an OLE2 document. POI can't handle very old office documents (pre about 95, but it varies between formats), but it can at least open the outer OLE2 container

Without the sample file I can't tell what your file actually is, but my best guess is that someone has renamed it to be .doc when it isn't anything like that

> I found an issue with the parse method of org.apache.tika.parser.microsoft.OfficeParser. This parser generates a Tika Exception when it try to parse very old file of Microsoft Word.
> I think this issue is not a priority because the files that cause the exception belong to an obsolete format/structure that even new Microsoft Office versions don't support them, but it's important to know that something wrong about these outdated types can happen.
> I report two links about old types (Microsoft support perspective):
> http://support.microsoft.com/?kbid=922850
> http://support.microsoft.com/kb/922849/it
> For example, the message of TikaException is below:
