We use the Scheduler control with Exchange to list known service outages. We show three different schedulers, all linked to the same provider, to show last week, this week and next week.

We have recently found that scheduler is not showing new appointments, although creating new appointments in scheduler does push them back to Exchange. Deleting old appointments (which is something we don't want to do) allows the requisite number of future appointments to show, so it would appear that:

1.) ExchangeSchedulerProvider is always retrieving appointments from the beginning of time

2.) There is a limit to the number of appointments retrieved that is too low for our requirements.

So my questions are:

1.) Can I set the provider to only retrieve appointments from a certain date?

2.) If not, can I increase the number of appointments retrieved (far from ideal).

Thanks.

Sorry for the delay. The code is very simple:

<table width="100%">

<tr>

<td class="GeneralMiddle" align="center">Last Week</td>

<td class="GeneralMiddle" align="center">This Week</td>

<td class="GeneralMiddle" align="center">Next Week</td>

</tr>

<tr>
