When working in OpenOffice with documents that will be accessed elsewhere by Microsoft Word, you must save the document as Word format.
To save a document in Microsoft Word format, click on the "File" menu.
Select the "Save As..." item from the menu.
The "Save As" dialog appears.
Click on the arrow of the drop-down list for the "Save as type: " field.
To define the type of the file, select "Microsoft Word ... (.doc)" item from the list.
Click on the "Save" button to finish the dialog.
By default OpenOffice.org warns you if a target file type can not save all formatting information.
Click the "Yes" button to confirm your decison.
