E-mail Tab, Hotmail and Attachments

[Tweak_four17]

So I finally got my hotmail to work properly in the ail tab (before it would launch opera and go to mail.live.com) anyways, it seems to be working well so far, except some attachmetns it won't download, comes up with an error saying the file is too large even though it is only 6mb, is this a quick reg fix or something deeper? also are the attachmetns that are downloaded stored on the phone or just put into a temp directory and then deleted? It would seem like they are just temp, but then is there a way to actually save them for keeps?
