I have 3 hundred clients in my address book with their birhtdays and anniversayrs etc. Those are full day events. When the clock adjusts for daylight savings it moves them all to another day either 1 ahead or behind and now I am off on what day I need to get stuff out to those clients all because Outlook screws up with time. See my problem?
So, when you create these appointments, you check the box for "All day event". Is that correct? Hmmm, are you an event planner? Otherwise, I can't imagine why you would need to create these appointments in that manner. I haven't used this feature with Outlook, but I suspect that if you stop creating your appointments that way, then won't have this problem. Even you are an event planner, why would you need to create appointments in that manner? I mean, seriously, how can you schedule 300 or more "all day events" in a year? Do you literally spend the entire day with your clients on their birthdays and anniversaries? When do you sleep? And, if you business is not event planning, when do have time to get any business done if you're basically scheduling the whole year for birthdays and anniversaries?
