I emailed Touchdown support with this question, but wanted to throw it by this forum just in case anyone knows or has the same issue:
In my Touchdown settings, I have UNCHECKED the box that says “Don’t Mark Read on server.” When I read the new email on my Motorola Droid X Touchdown application, it marks it as read on the Droid X, but does NOT mark it as read on the Exchange Server. (We have Exchange 2007 and I use Outlook 2007 as my desktop client.)
Conversely, if I read the message on my PC using Outlook, it will mark the message as read on the Droid X. Also, if I mark an email as unread in Outlook, it will sync that change on my Droid X.
Why will my Touchdown App not Mark the messages as read on the server?
