Microsoft Office product manager Reed Shaffner said, "Crashes are one of the most frustrating experiences customers have, and the team worked hard with SP1 to make our products more stable.
"We have also included most of the previously-released hotfixes that also help reduce the incidence of crashes in Office applications."
Shaffner said SP1 also provides key fixes and enhancements to make the 2007 Office system more reliable and easier to use. For example, SP1 addresses problems customers have experienced in Outlook 2007 when opening large mail files.
It also delivers more accurate presence information in Microsoft Office Communicator to help improve collaboration and communication for customers, he said.
"We also did a lot of work to improve the reliability of the 2007 Office system's server components with SP1. We know that search is really important to our enterprise customers using Microsoft Office Sharepoint Server 2007, so we spent a lot of time improving indexing to help make documents and information easier to find," said Shaffner.
SP1 includes support for Ajax deployments, which should help developers create custom web parts for their customers. SP1 also incorporates bolstered security technology to deliver better protection against malware, privacy intrusions and other threats, Shaffner said.
