PLEASE NOTE: Regarding Jim Goings's comment above:

We DO NOT suggest that you follow the procedure on the blog. Instead, you should contact Apple support and work with them to receive a fix.

Just posted an article on my blog with a fix for Exchange 2010 users. We got a NEW profile from Apple that reverts EAS support to 12.1. So far, 100% fix rate.

Ron - I work for a University and our users are also experiencing the issues with sending e-mail in iOS 4.0 and 4.0.1. It sits at "sending" 50% of the time. If you let it sit there, the phone heats up and eventually kills the battery. Do you know of any solution? Is Apple aware of this issue(admitting it/ working to fix it)? Users running iOS 3.x.x don't have this issue. We are running Exchange 2010 RTM.

Our single Exchange 2003 server gradually over the course of about 4 days came to a grinding halt after many of our users upgraded to the iPhone 4.

Last Friday I noticed that the full backup of our 275GB mailbox database took almost twice as long to complete (16 hours instead of the normal 8 hours). The next couple nights were equally bad, and then the business day started on Monday and almost immediately the normal daily email was queuing up and messages were being delivered up to 90 min late. The server just couldn't keep up, but this didn't really make any sense because everything was working properly, but it was just not fast enough. What possibly would cause such a sudden and large performance hit? Eventually we tracked down that it was the iPhones, so we stopped it at the firewall, witnessed Exchange start to improve almost immediately, and then we let the mail queues catch up. At that point we decided to open the necessary ports once again, and things remained fine for a couple hours until... all of a sudden the mail queues jumped way up again. The mailbox store actually began to refuse everything. Outlook clients wouldn't send mail at all at that point and got immediate bouncebacks, so of course our users weren't too happy about this, and neither were we. The application log was littered with events from Exchange, and I was extremely concerned about possible database corruption. The store.exe process was constantly churning away, but no mail was coming or going, and fortunately a simple restart fixed everything. But that was only after a lot of sweating since the previous few night's backup had not completed yet either.

We have since gone back to using just IMAP for now, so that our Exchange server can keep up until we upgrade to a 4-server Exchange 2010 solution next month, but of course our users want the calendar and contact sync functionality from ActiveSync, as well as the push email. I would love to see Apple and Microsoft address this immediately.

We are seeing messages stuck in Outbox on 4.0.1 phones (both iPhone 4 and 3Gs). Cannot recall having any reports of this prior to 4.0.1. Server is Exchange 2010 RTM RU2. No other mail accounts are configured on the iPhone.

We're stuck here .. want to require folks running 4.0.0 to upgrade to 4.0.1, but from the end user experience, 4.0.1 is worse then 4.0.0.

I should have said our configuration is Exchange 2010 R4 on Windows 2008R2.

I believe this is only happening for EWS clients (Entourage and the up coming Outlook for MAC 2011)

Synchronization with your iPhone failed for 1 items.
The following items couldn't be sent to your mobile phone. They haven't been deleted. You should be able to access them using either Outlook or Outlook Web App.

Item Folder: Inbox
Item Type: IPM.Schedule.Meeting.Resp.Pos
Item Created: 3/08/2010 3:09:25 a.m.
Item Subject: Accepted: Test 4

This not only effects iPhones also had this for Nokia devices. The problem occurs with the Accepted: or Declined: email that come back from booking a meeting with a resource or person. It is related to the unread/read mark.

In my client if I leave these Accepted/Declined messages unread I do not get the "Synchronization with your mobile failed for 1 items" once I have read the message I get the error. Basically what's happening (or not happening) is that the message remains unread on my mobile device. So the unread/read mark is not transferred to the mobile device.

When I then look at the message on the device it says "This message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. text/plain"

If I open an Accepted/Declined message on the device before it has been read on the client it reads fine "Your request was accepted"

It's like reading the message in the client is changing the format of the message some how.

Exchange 2010 does not seem to function through the Mail application in IOS 4 at all for me (though the "lite" version does seem to work in Safari). Are all these tests being done using previous versions of exchange servers?

We have several users on OS 4.0.1 that are stil experiencing issues when sending email. The process just hangs trying to send. It can sometimes be cleared by turning the radio off/on but generally requires a restart of the phone. How can Apple expect to have their phones used in the Enterprise and not address this big issue in a timely manner?

So what is Apple doing about this? We are now using VPN connections on the phone so the users can send email. Is there anything that can be done on our end without Apple's help to change a setting in Exchange or ISA to fix this? This is ridiculous!
