After some users with large Outlook 2007 Personal Folders (pst files) complained about the e-mail client running slowly, Microsoft released a patch last week that is said to improve the application's performance. According to the patch's description, it fixes two problems: the first where a calendar item is marked as private if it is opened by the Search Desktop feature, and the second being the performance issue.
Functionality that should become more responsive after applying the update includes:
- Downloading messages from Exchange
- Deleting messages
- Moving and copying messages
- Switching between messages
- Outlook startup
