php-ews class library always returns null
问题 I am trying to make SOAP calls to our Exchange server using the classes I found here: http://code.google.com/p/php-ews/ I have coded up a few examples, starting with the basic example as below and no matter what I try and do this always returns null. $ews = new ExchangeWebServices('exchange.example.com', 'user', 'password'); $request = new EWSType_FindFolderType(); $request->Traversal = EWSType_FolderQueryTraversalType::SHALLOW; $request->FolderShape = new EWSType_FolderResponseShapeType();
