Staff at IBM have been given ten days to stop using Microsoft Office and switch to the Open Office-based software Symphony, IBM’s in-house Lotus software. The use of Microsoft Office will in future require managerial approval. With immediate affect, the Open Document Format (ODF) will rule at IBM with the file ending .doc soon belonging to the past, reports Handelsblatt. Lotus Symphony is an office software that incorporates huge chunks of customized Open Office without a databank module. The free software download provided by IBM is an attempt at luring customers away from Microsoft. IBM’s cooperation with Linux distributors like Red Hat, Canonical and Novell was designed to strengthen the software’s market chances.
