Travel Technology - Outlook alarms - Any ideas?

I have an issue with Outlook and my boss and the (windows based) organiser which she is now using. The issue is that she has daily reminders set in the calendar for different days and they are usually set for the start of her working day so assume 7am (she likes them set for then) and then the alarm is set automatically 15 mins before that by outlook. This is the problem, she would like the alarms to ring only during say 9am to 5pm and we can't find a way of doing this automatically.

She could untick the alarm on everything starting before 9am, but will inevitably forget to do so and the chances of someone adding an appointment in without telling her are quite high. It is vital that the alarms sound during the day but not at silly o'clock in the AM. I will find out what sort or organiser it is when she gets back, but I think an HP from memory.

Does anyone know a work around for outlook so that she can set it up so that alarms only sound during the working day say 9-5?

The last organiser didn't make a noise but this meant that she could miss appointments.

If you have any thoughts please let me know.

Is the boss using Outlook or something else? Or is she syncing between the two somehow? And which one do you want to silence, Outlook or the other one?

Off the top of my head I do not know of any way to make Outlook only play a reminder during business hours.

Thanks for the reply, I think it's Outlook on both (I'm not in the office today so can't check) and she will leave it syncing when she is at her desk. The office computer doesn't matter it is just her handheld that causes the problems.

I'll check what the handheld uses and see what it actually does when it reaches a reminder - will be a right b*gger if it won't shut up outside office hours.

I don't believe Outlook has this capability. It sounds like a setting on her PDA/phone that needs to be investigated. I think my Windows Mobile phone has a quiet time setting somewhere.
