Scheduler with ExchangeSchedulerProvider not retrieving all appointments

[jwhitley]

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.

Hi John,

Can you send a sample project, so we can review your code?

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>

        <td>

What is the value of the ConfigurationManager.AppSettings["TheUser"], 
Try to put your email.

TheUser, ThePassword and TheDomain are all valid for the associated Exchange mailbox. I've just changed their names in the sample code. There are no credential issues, the ExchangeSchedulerProvider connects to Exchange just fine. TheUser is indeed an email address.

[Hristo Valyavicharski]

There is a bug in the provider, at the moment it can list only the appoints from the default calendar, which is associated with the user's email addresses.

That might well be a bug, but it is not my issue. The default calendar is what I need, but as per my original post, it is not reading all the appointments I want and it only seems to read appointments from the beginning of time, not just for the time period being displayed.

I will raise this as a support ticket instead as I need a faster response.
