Exchange and iPhone Attachment Size

Has anyone had issues with iPhone activesync with Exchange server and attachment size issues?
Got a client with an Exchange 2003 and 2010 server, in the middle of a migration. The problem is that only the iPhones cannot send attachments over 10mb. The droids can and of course the Blackberry's can (BES 5 server) The Exchange servers are patched fully.
Currently, all activesync users are on the 2003 server. Took one user and moved them to the 2010 server to test but same results. Attachment sizes on both Exchange servers are set to 25mb and sending over 10mb can happen from Outlook at the desktop.

When sending (forwarding mostly) the iPhone looks like its syncing and reads sending for about 6 minutes then fails.

Thanks for any input.

Your iPhones are probably hitting the default 10mb restriction set on the Exchange 2010 server now, so please increase the Receive settings according to the following article:

http://www.msexchange.org/articles-tutorials/exchange-server-2007/management-administration/exchange-2007-message-size-limits.html

The article is for 2007, but the settings apply to 2010 too.

Thank you for the reply - However, I don't think that is the issue. I mean, why would it only effect the iPhones and not droids or Outlook clients or OWA clients?
I will review all the settings on the server. Thank you.

Thanks alanhardisty - we have again went over all settings on the 2010 server.
We have checked the Global settings, the send connectors, the receive connector and the individual mailboxes in question. all are set to 25mb or larger. Including the activesync policy under the organization which has no check and thus I assume no limit. Am i missing something?

Thanks again.

On the same lines, E2k3 wont have any web.config

If someone still face the same issues w.r.to the E2k3 or IIS6.0
Then check for the presence of the "URLScan"

Note: Ensure that urlscan.ini shouldn't be there in the system.

Actually there is a web.config on Exchange 2k3. It is located at C:\Program Files\Microsoft Exchange ActiveSync Administration folder. At least on this one.

The string did not exist in that file so I appended the URL cmd - saved and iisreset.

Not to say it had any affect because I changed both the 2010 server and the 2003 server at the same time. We successfully tested attachments on iphones with mailboxes on both servers over 10mb.

I double checked my E2k3,IIS6.0 servers

Regarding the Microsof-server-activesync
Local Path: C:\Program Files\Exchsrvr\OMA\Sync
The content is empty

OMA:
Local Path: C:\Program Files\Exchsrvr\OMA\Browse
yes, this path should have the web.config

IMO, this web.config should affect\control just the OMA access and not the Microsoft-server-ActiveSync communication
