Hi av4u001
If you get a chance I was wondering whether you could test the following....
1) Ensure you have at least one POP email account set up on your device.
2) Create a new email (Subject: "Test" and body: "This is a test email") and send it to one of the POP email accounts configured on your device.
3) Check your inbox one minute later and observe the email arrives.
4) Either left-drag on the email to immediately send it to the trash bin OR click on the email to read it (it displays correctly at this stage) and then hit the trash bin icon to send it to the trash bin.
5) Select the Trash Bin and observe the email you have just deleted. It should have the correct subject text but what does it display for the email body text? It should read "This is a test email".
Does it read "This message has no content" instead?
If it reads "This is a test email" then you aren't seeing the problems that several others including myself are experiencing here.
Otherwise read on.
6) Still in the Trash Bin, click on the email.
What does the body text read?
Obviously it should read "This is a test email" but does it instead display "This message has not been downloaded from the server"?
7) Click the folder icon (move email) followed by the sent icon (to move the email to your sent box). I realise that this will rarely be desired but it should still work correctly however.
8) Select your sent box.
Is the email sitting in your sent box or has it now completely disappeared from your device (not in your sent box and no longer in your trash bin)?
I can demonstrate these issues with 100% success rate so anytime apple feel like addressing the on-going problems with their awful mail app, bring it on.
