Messages that I reply to from my phone are placed in the "Sent" folder. Is it possible to configure the Email App to place replies in the same folder as the original message. Using galaxy S3, Android 4.0.4.
As far as I can tell, no, there is not a way to configure where sent mail is placed using the IMAP email account on the Galaxy S III. There may be a 3rd party email app that can do this, but not the stock one on the S III. As suggested in the comments K-9 Mail does what you want.
