For those of you who noticed the date mistake in my last tip, one problem Outlook doesn't have is getting the date wrong. That was all me. How will I ever make it through 2006 if I'm still writing 2004 in Dec of 2005? <g>
However, there are numerous reports that users are unable to create new Calendar items after installing Outlook 2003's SP2. While we have no idea what is causing it and it doesn't appear to be very widespread, the solution is to restart Outlook. If Outlook doesn't close completely (look in Task Manager) you'll need to force it closed (select Outlook.exe and click End Process), otherwise you'll need to reboot. So far, everyone affected by the problem reports a restart (or reboot) the problem.
