PHPEWS create event on public calendar - php

Question

I'm attempting to plug a php based calendar management system into exchange 2007 calendars.
I have the below code setup at present.
$subject = 'Appointment with ..';
$request = new EWSType_CreateItemType();
$request->Items = new EWSType_NonEmptyArrayOfAllItemsType();
$request->Items->CalendarItem = new EWSType_CalendarItemType();
$request->Items->CalendarItem->Subject = $subject;
$date1 = new DateTime('2015-05-10T15:00:00+03:00');
$DateStart = $date1->format('Y-m-d H:i:00');
$date = new DateTime($DateStart);
$request->Items->CalendarItem->Start = $date->format('c');
$date1 = new DateTime('2015-05-10T17:00:00+03:00');
$DateEnd = $date1->format('Y-m-d H:i:00');
$date = new DateTime($DateEnd);
$request->Items->CalendarItem->End = $date->format('c');
$request->Items->CalendarItem->ReminderIsSet = false;
$request->Items->CalendarItem->ReminderMinutesBeforeStart = 15;
$request->Items->CalendarItem->Body = new EWSType_BodyType();
$request->Items->CalendarItem->Body->BodyType = EWSType_BodyTypeType::HTML;
$request->Items->CalendarItem->Body->_ = <<<EOD
<p><strong>Staff Attending</strong>:bob</p>
EOD;
$request->Items->CalendarItem->ItemClass = new EWSType_ItemClassType();
$request->Items->CalendarItem->ItemClass->_ = EWSType_ItemClassType::APPOINTMENT;
$request->Items->CalendarItem->Sensitivity = new EWSType_SensitivityChoicesType();
$request->Items->CalendarItem->Sensitivity->_ = EWSType_SensitivityChoicesType::NORMAL;
$request->Items->CalendarItem->Categories = new EWSType_ArrayOfStringsType();
$request->Items->CalendarItem->Categories->String = array(
'Client Meeting (Scheduled)'
);
$request->Items->CalendarItem->Location = "Showroom";
$request->SendMeetingInvitations = EWSType_CalendarItemCreateOrDeleteOperationType::SEND_ONLY_TO_ALL;
$request->Items->CalendarItem->RequiredAttendees->Attendee[0]->Mailbox->EmailAddress = "user#domain.com";
$request->Items->CalendarItem->RequiredAttendees->Attendee[0]->Mailbox->RoutingType = 'SMTP';
$n = 1;
$response = $ews->CreateItem($request);
This will setup an event in the users personal calendar just fine, but what I need to do is to get it to post to a public folder calendar which I have the folderID for.
If anyone could assist it would be greatly appreciated!

Answer 1

Try adding the line:
$request->SavedItemFolderId->FolderId->Id=$folder_id;
after the
$request = new EWSType_CreateItemType();
where $folder_id is your stupidly long microsoft folder id!!!!

Answer 2

I'm doing the same right now.
You have to replace the SEND_ONLY_TO_ALL with SEND_TO_NONE.
This means that we cannot send meeting invitations for appointments stored in a public folder (I've been trying to find a workaround for this problem for a couple weeks now).
I'm not sure if there are other problems in your request but this is surely an issue.
