Same problem here, email does not thread for my Gmail or my Exchange account. I was really Looking forward to this feature. I even deleted and then re-added my Exchange account and still no threading. Anyone find a solution?
Well, since my last entry here I've reset my IPad and the mail now threads.
I was expecting my IPad Mail would group the sender's names together as Mail does on my IMac but it doesn't.
Unless there's something I don't know....
Threads works for me, BUT I am getting Threads that are "from the future" and have not yet appeared in my inbox!
I will tap on an email showing a thread count, and more emails from that thread will display, but these have not yet shown up, nor do show up in my inbox....
I can click on them and return to the inbox, but they are still not there....
Very odd.
Ok, I think I understand what is happening:
Consecutive emails in the same thread are displayed as a single email and only expand when tapped into thread view.
Whichever email is last looked at before collapsing to the inbox is then the only one displayed in the inbox.
I guess I need to read the manual on how Mail on the iPad for OS 4.2.1 works, if one exists...
Seems a bit counterintuitive if you are awaiting a response from one particular person in a thread...no way to know they have replied without opening the thread or constantly checking the thread count number.....
Yeah, threading is based on subject not person, as it is in Gmail. If all messages in a thread are read, if you are in the main inbox when a new message comes in, the displayed message for the thread will show as being from the person who sent the oldest unread message in the thread. So yeah, if you're looking for a specific responder, unless they are the next one, you'll have to keep checking the thread.
As a note, even though you'll be seeing the sender of the oldest unread message (and a preview of that message), the time displayed on the thread will be for the NEWEST message. That is definitely counterintuitive, but at least it will help you know when the latest message in the thread came in.
