We are creating Excel-XLS files with Apache POI (Version 3.10.1-20140818). Now one of our customers is having some problems with these files. When he tries to open it with Microsoft Excel 2007, he gets a warning "Sicherheitswarnung - Office-Dateiüberprüfung" (see warning.png in zip-archive) and he has to click on "Öffnen" (open) each time he tries to open one of our excel-documents. I guess that this warning is like what is described in http://support.microsoft.com/kb/2501584/de respectively http://support.microsoft.com/kb/2501584/en

So i created a simple demo file and tested it with the "Microsoft Office File Validator". The file failed the validation test. Also the "Business Plan"-Example (http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/ss/examples/BusinessPlan.java) failed this validation test.

The output of BiffViewer was no help to me.

Can You help me?

You will find all files in the attached ZIP-file.

Kind regards,
Alexander Roskamp
