Important - Deprecation of Notes in Exchange Server
The Notes store is mainly present in newer versions of Exchange for legacy reasons. Creating notes is only supported officially in the Outlook client.
It is not possible to create or edit Notes in Outlook Web App, although you will be able to view and delete them.
The ActiveSync client in Windows Phone does not support Notes at all.

Algorithm / XML documents

Synchronizing all notes is a three-step process:
The "Type" for "Default Notes" is "10". (Can be found in the EASProtocol.Enums.FolderSyncTypes.DefaultNotes.)
"User Created Notes"-folder has not been implemented yet.

The XML documents used are the following

Discover Folder Ids:
<?xml version="1.0" encoding="utf-8"?>
<FolderSync xmlns="FolderHierarchy">
  <SyncKey>0</SyncKey>
</FolderSync>

Get SyncKey:
<?xml version="1.0" encoding="utf-8"?>
<Sync xmlns="AirSync">
  <Collections>
    <Collection>
      <SyncKey>0</SyncKey>
      <CollectionId>FolderId</CollectionId>
    </Collection>
  </Collections>
</Sync>

Get Notes
<?xml version="1.0" encoding="utf-8"?>
<Sync xmlns="AirSync">
  <Collections>
    <Collection>
      <SyncKey>SyncKey</SyncKey>
      <CollectionId>FolderId</CollectionId>
    </Collection>
  </Collections>
</Sync>

The API will return something similar to this (in JSON format):
  [
    {
      "Subject":"Test Note",
      "MessageClass":"IPM.StickyNote",
      "LastModifiedDate":"20130816T150215Z",      
      "Category":"Business"
    }
  ]
