Microsoft Corp. is updating its OneNote note-taking application with a service pack that adds significant new features, including ones that increase Office integration and support syncing with Pocket PC notes. A preview version of OneNote 2003 Service Pack 1 is scheduled to be available as a free download from Microsoft’s Web site. Microsoft plans to release the final version shortly after the company launches SP1 for Microsoft Office, which is expected this summer, says Bobby Moore, OneNote product manager.
