Enterprise Vault with Exchange 2007 LTM+APM

First, ASM is incompatible with Outlook, so you should remove that policy from the virtual server, or deploy separate virtual servers for each service if you want to protect OWA and ActiveSync with ASM.

Including EV in the existing iRule would involve asking addtional questions that would lengthen both the iApp and deployment guide, which is something nobody wants. :-) I recommend using the iRule attacher in the iApp to get this done for now.

We don't have a guide for EV and I don't expect us to do one, unfortunately. You may want to consider involving F5's Professional Services here, especially since our Exchange solution is targeted at 2010 and 2013 only and you have a lot going on here with APM and ASM.
