Q: Can I send a draft email created on my desktop from my iphone?  The mail account is Microsoft Exchange

I often create complex emails on my desktop at work to multiple addressees and then want to send them later in the evening from my iphone.  The message is saved as a draft in the drafts folder on my outlook email account on the desktop but I can't see a drafts folder on the exchange account on my iphone.  Does anyone know if it is possible to synchronise drafts to an iphone?
