Is there a way to make libreoffice compatible with Microsoft office? Do I just need it to be in the same file format? Or will it still mess up each other?
For basic documents, saving LibreOffice documents as Microsoft Word 2007-2013 XML is just fine. If you are collaborating with others on a document and formatting matters, particularly if you have embedded images, track changes, comments, et al, then I recommend agreeing with your collaborators on using either LibreOffice or Microsoft Word. There are too many small things that get lost in translation that can be a huge time suck. As an Ubuntu user, I pitch LibreOffice for collaboration but have MS Word 2010 installed under Wine as a fall-back. Wine support for MS Office 2010 is excellent, rock solid.
