Steps to Reproduce
1) Go to control panel and update the mail domain to something other than liferay.com (e.g. test.com)
2) Create a new Word Document from Sync and check that it exists in Document Library
3) Update the Word Document from Sync and see that version is 1.1 and changes persist.
4) Copy the Header from .docx file (attached) to the new document's header. The version should update to 1.2 and the change should persist.
5) Try to update the document body one more time and assert the file is not updated and the Sync logs show that the company could not be found
