Q: After ios9 update my emails with attachments won't open and say "message not yet downloaded from server". They were there previously. How do I get them back?

Same here; NO improvement with 9.1 update.

SSame here. 9.1

Wrong. No difference on my iPhone 6 Plus

Since your phone seems to be the only one working please share which iPhone you have.

i Am still showing an update for 9.0.2 on my iPhone 5s.  usually it should be replaced with the 9.1, is anyone else having this problem?

i Really do not which to download the 9.0.2 since it came with many other problems which I wish to avoid.  Dealing with this message not downloadEd from server is plenty.

After updating to IOS 9.1 it may be advantageous to delete and recreate your POP email accounts to enjoy the fix.

Warning....unless you have them stored elsewhere you will lose any emails you have associated with those accounts.

So far so good with my experience of POP email and IOS 9.1

Fear not, I shall endeavour to report back the instant anything goes awry!

I did precisely that, but the issue is still present on Ios 9.1 on my iPad 3, even with a small 23KB message that appears to be entirely text (with a couple of URLs) that I had moved from my Inbox to my archive pst on my laptop, which now shows the dreaded "This message has not been downloaded from the server".

Switching off wifi results in embedded images not being displayed even if the email still resides on the POP server - a moot point given they couldn't access them with wifi off, but it illustrates another aspect of io mail's new storage philosophy..

Am I the only one that's concerned that "senior" Apple techs think it's OK to call my local mail storage a 'cache' that they can unilaterally tidy, and that a fix in 9.1 concerning POP email unread error counts might have anything to do with our issue? Geniuses? Don't make me swear...

One thing we need to understand is that all messages that have been affected by the issue 'before' the 9.1 update will still ALWAYS display the same error when trying to access them even after the 9.1 update has been applied, unless you have those affected emails downloaded into your MacBooks/Laptops, they are irretrievably lost forever.

However, yesterday's 9.1 update has now addressed this issue with newly received emails AFTER the update has been installed, well, it certainly has in our case!   All new POP emails received in our devices (iPhone 6's or iPad Airs) after the 9.1 installation, now remains in the Apple Mail app, exactly how it should, even after those emails have been removed from the POP mail servers.

My team of 12 staff, including myself, all use iPhone 6's  and iPad Airs now running on iOS 9.1 and, so far, NONE of us are experiencing the same issues with 'messages not downloaded from the server.', like we were before the update was installed.

How long since the emails were first downloaded? Mine seemed to go in less than half a day...

Lucky for you ( so far!) I have to report that in my case IOS9.1 has not cured the problem and the contents of my emails disappear shortly after arriving in my Inbox and are replaced by "This message has not been downloaded from the server"

Before 9.1 was installed, our messages were disappearing from our devices from 30 minutes to 12 hours after the emails have been removed from the POP mail servers.

Most of us installed the 9.1 update last night shortly after release, since then, we have received a plethora of emails on our devices which have also now been removed from our POP mail servers, it has now been nearly 24 hours since 9.1 was installed and everybody in our team are still able to retrieve their emails together with their full content on our iPhones and iPads.

That's great for the iphone 6 users but what about the iphone 5s?

Will Apple be retracting the 9.02  software update from my phone and replace with the 9.1?

I am still not seeing it on my phone.

I 'think' you might need to install 9.0.2 on your 5s before the device will prompt you to install 9.1...like I say, that is only an 'assumption', is somebody able to verify this?

In my experience, this issue has NOT BEEN SOLVED. I downloaded 9.1 yesterday morning. I immediately deleted the two accounts that I'd left on my phone--both--POP3--and recreated them from scratch. I had yet to change my PC settings to delete emails from the server once read, so I was able to retrieve all email sitting on the server for both accounts as FRESH COPIES. Once downloaded to the phone, I went into my mail server and deleted all those emails. Of course, they remained on my PC having already retrieved them there. At this point, I changed the settings on my email client on my PC to remove emails from the server once read, so that future emails would not remain and clog the server. As is the case with POP, if I have not downloaded them to my IPhone first, I should not be able to retrieve them once read on my PC--fine, that's how it's supposed to work, however all the emails I downloaded prior to this should be on the phone. Within 24 hrs, I am now getting the dreaded "This message has not been downloaded from the server" for some emails. Apple still has an issue with caching as opposed to actually downloading the email to the phone. How do I know this? I ran a test on one of the email accounts for which I had read an email last night. This morning, I put my phone in airplane mode and did not activate WIFI. I went to this account and tried to read this email. I got the bleeping message. I then went back to settings and took it off airplane mode. Went back into the account and I was able to read the email!!! Apple's email client is still not loading emails on the phone, just the email header which is why we can all see the first couple of lines. This WAS NEVER THE CASE PRIOR TO IOS 9.x. I had sent and received emails on my phone from a year and a half ago that I was always able to retrieve even though they had been deleted from the server looong ago. FInally, I still have not heard anyone explain why sent emails, COMPOSED ON THE PHONE, do not remain on the phone. The IPhone is now completely useless as an email device.

Thank you for putting it so succinctly.

I think that since I can no longer set up a POP account without "fooling" the system it means that Apple has decided not to support POP accounts any longer and that is why we are not getting anywhere with AppleCare.

Thank you for the detailed post conveying your good detective work which I just emailed to the Sr Tech Advisor monitoring my open case with engineering.  I too did the iOS9.1 update, then deleted and recreated my POP3 mail account and have this same issue.

What I can't wrap my head around is why this bug should have impact on messages in the Sent mailbox.
