Hi.
We are experiencing that when a user opens more than about 70 calendars.
Outlook fails with the message like "Unable to display the folder. The
information
store could not be opened".

Actually we found the problem because we have an app which reads all
calendars (using the COM interface to Outlook) and it fails when it reaches
about 70. So we reproduced the problem by manually doing the same thing. For
some reason the COM interface adds the calendar folders in the "People's
Calendars" list in the left side of Outlook.

This is Outlook 2003 SP2.
Has anybody else seen this, or know a fix for it?

Best regards,
Rasmus

Why do you need to *simultaneously* open that many folders?

The calendar information is needed in a telephone switchboard application. -
The user has a list of all coworkers where their daily schedule is shown.

The calendars are read similar to this:
outlook = GetActiveOleObject('outlook.application');
namespace = outlook.GetNameSpace('MAPI');
while more contacts do
contact = namespace.CreateRecipient(otherusersalias);
calendarfolder = namespace.GetSharedDefaultFolder(contact,
olFolderCalendar);
calendaritems = calendarfolder.Items;
calendaritems.Sort('[Start]');
calendaritems.IncludeRecurrences = true;
restriction = '[Start] = midnighttoday and [End] = midnightyesterday';

while more items do
// read calendar times
done;
calendarfolder = Unassigned;
done;

I'm assuming that the final Unassigned assignment will close the folders,
and remove references?

Is there something missing, or should it be done differently?

Thank you.

Best regards,
Rasmus

You need to release *all* the variables that point to the objects from that
mailbox (calendaritems, calendarfolder).
Move the code that opens and process a particular mailbox to a separate
sub - this way all local variables will be automatically released when the
sub exits.
If you are using .Net, GC.Collect would also be a good idea.

I am using Delphi, so no garbage collection.
I am pretty sure that all variables are now set to Unassigned after every
calendar read, but the problem prevails.

Is there a way to remove a calendar from the "People's calendars" list in
Outlook?
I wonder why the other peoples calendar's are added to that list, when our
program reads the calendars using the object model. But maybe if the program
could remove the entries from that list after Outlook has added them, we
would be able to work around the problem.

Delphi releases all interface type variables when they go out of scope, i.e.
when the method where they are declared exits or, in case of the class
variables, the class is destroyed.
Are you using multiple dot notation?
Again, do try my suggestion and see if it helps.

Hi Rasmus

I am not able to help you with this problem of 70 calendars, but I am doing
a similar project, i.e. writing an application that reads all calendars for
use by a telephone switchboard.

Have you solved the problem of not getting any info about private
appointments that people may have in their calendars? I mean, not the details
of the private appointments, but that there exists a private appointment and
start and end time of the appointment.

I have been searching for days now, but have not yet found any solution.
Have you? I am using write in VBA in Excel.

Jim
