This is extremely interesting and, as you know, I am comparing to Touchdown which I have used for years and Nine which I just bought before testing and selecting AM. With Touchdown, there was an option to Defer syncs to save battery power. The problem with that is that, when I read a message and then filed it quickly, it would file it as unread. When I went back to Outlook, I would have tons of unread filed messages. But I created a search folder to see those and quickly mark as read. It was annoying but it worked. If I left it in my inbox for a while longer, eventually the read status would transfer and I could file properly. And I don't think I ever sent a read receipt.
I e-mailed Nine yesterday and received this response:
"Nine synchronizes with Server using ActiveSync protocol.
If the received email is changed to mark as read, the server sends the read receipt email immediately. It can't be controlled by client.
If the status of mark as read/unread does not sync to server, the read receipts email won't be sent.
You can set the options with the following steps.
- Settings >> General >> Advanced >> Mark as read / Synchronize with server <= Disable"
I guess deferring updates doesn't really work when I am pulling mail every 10 minutes. Are there any other options to avoid sending a read receipt?
