I've seen similar discussions, but the resolution is to install Update Rollup 4 for Exchange Server 2007 Service Pack 1. However, we're experiencing this on Exchange 2010 and Outlook 2010. Problem: create an all-day event with no reminder, and invite an attendee. The attendee always gets a reminder pop-up, even if they uncheck "default reminders" in file/options/calendar/calendar options. It appears that this was a bug in 2007, was patched, but has returned in 2010. Any fix ideas out there other than our current "just live with it" plan? ______________________________________ Posted from http://outlook-center.com Outlook forums, articles, tips.
