Exchange users on iOS 4 need an updated config profile

FYI, I tried this and it wasn't working. The reason was because I had the FTP on the Go app installed and it apparently associated itself with the ".mobileconfig" file extension, which is what this exchange config file was. So, Safari kept asking me to open it with FTP on the Go, and not the system settings, as it should have. To be able to install, I had to delete FTP on the Go and then redownload it in Safari.

My iPhone 4 was working fine, but I decided to install the profile after reading about it, just to head off any potential future issues. It messed up my inbox; e-mails from a couple weeks ago were showing up on the iPhone that weren't in Outlook or Outlook Web Access. No matter how many times I restarted the phone or refreshed, the e-mails wouldn't go away.

I ended up having to remove the profile, then delete my Exchange account on the iPhone and add it again. I don't know why the profile caused phantom e-mails to appear, but I'm definitely staying away from it on my iPhone 4.

We got a company-wide email on Tuesday stating (company name removed):

"[We are] aware of an issue affecting iPhone devices with the latest operating system (iOS4) causing Exchange ActiveSync Mail, Contacts, or Calendars not to sync, or sync very slowly. The issue can also cause [our] Exchange servers to suffer degraded performance, thereby impacting e-mail services for all [of our] people. "

We were given a link to the profile patch. What's funny is that my co-worker was able to install this directly from his iPhone, where as I had to download it and email it to myself via my laptop. When I tried from my iphone, I just got a page with an image of the file.

Anyway, it worked. Syncing is faster, battery is back to "normal" for my 3GS.

I'm sick of Apple's neglect of the enterprise market. Why on earth didn't they properly test this?? Unbelievable!

I will be moving to Android, at least with apps like Touchdown you have a supplier who's focused on enterprise and is not obsessed with trivialities.

iOS = freedom from choice.

cleaning up your gmail account (deleting trash, all emails from half a year ago, etc) has made my gmail exchange account work again. shouldn't have had to do it, but it worked.

Still have the issue with home screen lock, and the 'continue search on server' does not actually search the server.... IMAP for now, sadly.....

PS this method of changing config files via a browser download (or I guess SMS message too) is cool. Can this be used for anything else?

Yes this is a fix. Found this about 4 days ago due to high network traffic at multiple Exchange Sites within our environment. We have around 70 Exchange Servers spread over a wide area (Australia).

We noticed network traffic from our BE Exchange Servers to our FE Exchange Servers after the iOS 4 upgrades.

I created a bit.ly link to the Config Profile download which I SMS to affected users that have already upgraded. I recommend running the Config Profile on our iOS 4 devices that sync via Exchange ActiveSync.

Also MS Exchange blog have posted an article about this issue.

I did this this afternoon, after searching message boards for an hour, I found a link to the profile update. Seems to be working fine for me on the 3G.

This fix definitely doesn't work entirely.

The use case seems to be (at least for us) users with very large (thousands of items) Inboxes. Users that keep their Inbox small (by moving items to other folders) seem to be okay even without the modified profile.

None of these users had any issues in 3.x; so it's definitely a 4.0 issue. We are hoping for a fix soon!

This doesn't fix ActiveSync issues with Gmail for me. Going back to IMAP.
