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.

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

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

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
