Receive email after a certain date using php-ews (Exchange Web Services)

In my PHP script, I need to figure out how to get all emails that are either after the specified message identifier or after a certain date (any of them will work, I just need to get emails that are new since the last time I cleared the folder " Inbox ").

This mailbox receives thousands of emails per day, and I cannot delete emails within 30 days. For the initial import, I just did an offset from the very beginning of the Inbox, but obviously this will not work when we start clearing emails.

I think I need to set the $ Restriction property of the EWSType_FindItemType class , "but I don’t think the necessary classes exist in php-ews for me to do this. I tried to add them myself, but I am not good at EWS or SOAP.

So far, the only thing I've come up with is:

$Request->Restriction = new EWSType_RestrictionType();
$Request->Restriction->IsGreaterThan = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURIOrConstant = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURIOrConstant->Constant = '2012-01-02T07:04:00Z';
$Request->Restriction->IsGreaterThan->FieldURI = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURI->FieldURI = 'item:DateTimeReceived';

And this does not work :(

Here is the code I use to receive email:

<?php
require( dirname( __FILE__ ) . '/ews/ExchangeWebServicesLoader.php' );

$ews = new ExchangeWebServices( EXCHANGE_HOSTNAME, EXCHANGE_USERNAME, EXCHANGE_PASSWORD, ExchangeWebServices::VERSION_2010_SP1 );

$Request = new EWSType_FindItemType();

$Request->ItemShape = new EWSType_ItemResponseShapeType();
$Request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::ALL_PROPERTIES;
$Request->ItemShape->BodyType = EWSType_BodyTypeResponseType::TEXT;
$Request->ItemShape->BodyTypeSpecified = true;

$Request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;

$Request->IndexedPageItemView = new EWSType_IndexedPageViewType();
$Request->IndexedPageItemView->MaxEntriesReturned = 25;
$Request->IndexedPageItemView->BasePoint = 'Beginning';
$Request->IndexedPageItemView->Offset = $offset;

$Request->ParentFolderIds = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$Request->ParentFolderIds->DistinguishedFolderId = new EWSType_DistinguishedFolderIdType();
$Request->ParentFolderIds->DistinguishedFolderId->Id = 'inbox';
$Request->ParentFolderIds->DistinguishedFolderId->Mailbox = new EWSType_EmailAddressType();
$Request->ParentFolderIds->DistinguishedFolderId->Mailbox->EmailAddress = 'sharedmailbox@company.org';

// sort order
$Request->SortOrder = new EWSType_NonEmptyArrayOfFieldOrdersType();
$Request->SortOrder->FieldOrder = array();
$order = new EWSType_FieldOrderType();
$order->FieldURI = new stdClass;
$order->FieldURI->FieldURI = 'item:DateTimeReceived';
$order->Order = 'Ascending';
$Request->SortOrder->FieldOrder[] = $order;

$response = $ews->FindItem($Request);
$items = $response->ResponseMessages->FindItemResponseMessage->RootFolder->Items->Message;

foreach ( $items as $item ) {
    // Do stuff
}

Any help would be greatly appreciated!

The limit is limited in EWS, true. You can take a look at haw, they are used in EWSWrapper , here is an example of how to create an AND constraint to get elements between date ranges:

//create AND restrction
$request->Restriction = new EWSType_RestrictionType();
$request->Restriction->And = new EWSType_AndType();

$request->Restriction->And->IsGreaterThanOrEqualTo = new EWSType_IsGreaterThanOrEqualToType();
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI = new EWSType_PathToExtendedFieldType;
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->DistinguishedPropertySetId = "Task";
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->PropertyId = "33029";
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->PropertyType = "SystemTime";
$request->Restriction->And->IsGreaterThanOrEqualTo->FieldURIOrConstant->Constant->Value = date('c', $start);

$request->Restriction->And->IsLessThanOrEqualTo = new EWSType_IsLessThanOrEqualToType();
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI = new EWSType_PathToExtendedFieldType;
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->DistinguishedPropertySetId = "Task";
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->PropertyId = "33029";
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->PropertyType = "SystemTime";
$request->Restriction->And->IsLessThanOrEqualTo->FieldURIOrConstant->Constant->Value = date('c', $end);

And the types used:

class EWSType_RestrictionType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_SearchExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'SearchExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class RestrictionType

<?php

class EWSType_AndType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_MultipleOperandBooleanExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'MultipleOperandBooleanExpressionType',
        ),          
    ); // end $this->schema
} // end function __construct()
} // end class AndType
class EWSType_IsLessThanOrEqualToType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_TwoOperandExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'TwoOperandExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class IsLessThanOrEqualToType


class EWSType_IsGreaterThanOrEqualToType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_TwoOperandExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'TwoOperandExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class IsGreaterThanOrEqualToType

PHP- - PHP (php-ews).

( , EWSType).

$start = new DateTime('2013-03-31'); 

$Request->Restriction = new EWSType_RestrictionType();
