I have an Asus TF300 and was just setting up my two email accounts with the native mail app. One email acct is an exchange acct and the other is a Yahoo IMAP. Both come into the same mail app. Question; when I reply to an email i cannot change the 'from' account (like I can on my Android phone). Is there any way to set this up so I can select account on reply? Do I need to set up two different mailboxes (if that is even possible)? I like all my mail in one location so using the Yahoo mail app is not really an option (plus it sucks). Any ideas?
