To Do List

EWSAutoDiscover

Fix this shit up some day
Unit test what's fixed

HttpPlayback

Probably move to it's own library

All Types

Add a dirty/clean state to objects, so you can do $api->updateItem($items) and have it know what to update

Test Coverage

Increase to at least 90%

Compatibility

Think about swapping out Guzzle to reduce PHP version requirement to 5.4

Code Generation

Modify generator to include the SOAP functions as Doc Blocks on ExchangeWebServices class

Features

Create interfaces for at least the API classes
Merge getFileAttachments() and getItemAttachments() to getAllAttachments() in NonEmptyArrayOfAttachmentsType
Implement ItemType::getAttachments($attachmentType = null) to allow selection of certain types of attachments
When you fetch a list of items, certain information is discarded in the drilling down like the offset, if all items are in the view or if this requests contains the last item in the list. There's also no easy way to get a list starting at an offset. This should be fixed
Allow drillDownResponses to be optional. Or at least part of it. There should be a way to get richer responses if desired

Incorrectly returned values

ItemType::getCategories() return a stdClass with a property String which holds the categories, rather than returning them directly

Feature

Implement a "Always return as Array" feature (Will break BC)
