OK. I have the Samsung Note and recently upgraded it to Ice Cream Sandwich. I am using the installed default mail app to read my corporate Exchange mail. On Sync Options I have Peak schedule set to Push and off-peak schedule set to Push. If I read an email on my Note, it will show as read on my note, BUT it will *NOT* show as read in my Outlook client on my work desktop. If I move an email to another folder on my Note, the email will move to that folder and Outlook shows that the moved email is indeed in that folder. So it is syncing as far as moving messages to folders, but updating the mail on the corporate server does not work for reading when done on the Note. This did not happen with Gingerbread. All email read on the Note showed as read in Outlook. Any ideas? Am I missing a setting somewhere? Oh and when I read an email in Outlook, it will show as read on my Note. So it works in one direction but not in the other direction!
