How to get all subfolders from "root" recursively via SOAP from Exchange? - php

Question

After searching the web for hours you are my last hope:
I have to build a system which reads sent and incoming mails from a Microsoft Exchange Server. I found the following script for that:
Exchange-Web-Services-for-PHP (Heartspring)
https://github.com/Heartspring/Exchange-Web-Services-for-PHP
The existing get_messages() function returns all messages for a folder, for example "inbox". So far everything is clear. My problem starts when I want to get all messages from "sent" - Folder - i've tried many words, from "send" to "Sent Items"; without any result (mailbox not available)
My idea was to get all subfolders for the folder "root" and wrote this:
include "init.php";
$ec = new ExchangeClient();
$ec->init("bambullis#123.de", "", NULL, "https://amxprd3610.outlook.com/EWS/Services.wsdl");
$folders = $ec->get_subfolders("root");
foreach($folders as $folder) {
print_r($folder);
}
This is what I get:
stdClass Object
(
[FolderId] => stdClass Object
(
[Id] => AAAeAGJhbWJ1bGxpc0BzdHVrZSbi5kZQAuAAAAAABw352p5E4yS5voYF9ELBmiAQBXYPdO6NZAQ6T9C3xviT7xAAAAC1iXAAA=
[ChangeKey] => AQAAABYAAABXYPdO6NZAQ6T9C3xviAALNCey
)
[DisplayName] => Oberste Ebene des Informationsspeichers
[TotalCount] => 0
[ChildFolderCount] => 16
[UnreadCount] => 0
)
(I know that FolderId->Id is base64 encoded, I've modified the string above for security reasons ;o))
Now I tried to list the subfolders for this directory (I added a mailbox to see, if the value "ChildFolderCount" will change, it does):
...
print_r($folder);
print_r($ec->get_subfolders($folder->FolderId->Id));
...
This is the error I get:
The request failed schema validation: The 'Id' attribute is invalid
What did I do wrong? How to get all subfolders from "root" recursively? Thanks to this lovely guy who can help me!

The EWS-PHP get_subfolders method uses by default a TraversalType "Shallow", so it searches only the identified folder and returns only the folder IDs for items that have not been deleted.
To search in all subfolders of the identified parent folder and return only the folder IDs for items that have not been deleted you should use the "Deep" TraversalType.
For example:
<?php
include "init.php";
class myExchangeClient extends ExchangeClient {
public function get_subfolders_deep($ParentFolderId = "inbox", $Distinguished = TRUE) {
$this->setup();
$FolderItem = new stdClass();
$FolderItem->FolderShape = new stdClass();
$FolderItem->ParentFolderIds = new stdClass();
$FolderItem->FolderShape->BaseShape = "Default";
/*
** See http://msdn.microsoft.com/en-us/library/exchange/exchangewebservices.folderquerytraversaltype(v=exchg.140).aspx
** Deep Traversal: Searches in all subfolders of the identified parent folder and returns only the folder IDs for items that
** have not been deleted.
*/
$FolderItem->Traversal = "Deep";
if ($Distinguished) {
$FolderItem->ParentFolderIds->DistinguishedFolderId = new stdClass();
$FolderItem->ParentFolderIds->DistinguishedFolderId->Id = $ParentFolderId;
} else {
$FolderItem->ParentFolderIds->FolderId = new stdClass();
$FolderItem->ParentFolderIds->FolderId->Id = $ParentFolderId;
}
$response = $this->client->FindFolder($FolderItem);
if ($response->ResponseMessages->FindFolderResponseMessage->ResponseCode == "NoError") {
$folders = array();
if (!is_array($response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder)) {
$folders[] = $response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder;
} else {
$folders = $response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder;
}
return $folders;
} else {
$this->lastError = $response->ResponseMessages->FindFolderResponseMessage->ResponseCode;
}
}
}
$ec = new myExchangeClient();
$ec->init("bambullis#123.de", "", NULL, "https://amxprd3610.outlook.com/EWS/Services.wsdl");
$folders = $ec->get_subfolders_deep("root");
echo "<pre>".print_r($folders,true)."</pre>\n";
?>
Anyway, looking at the ExchangeClient class source code, the FolderID for the sent items should be "sentitems".
