Mac Outlook can't connect to Exchange 2007

I have a SBS 2008 running Exchange 2007
Few weeks ago mac clients complain that they can't send attachments larger than 2 mb.
After researching the web I modify the :\Program Files\Microsoft\Exchange Server\ClientAccess\exchweb\ews\web.config and change the value to <requestLimits maxAllowedContentLength="60000" and run c:\Windows\System32\inetsrv>appcmd set config "SBS Web Applications/ews" -section:requestFiltering -requestLimits.maxAllowedContentLength:60000
Now Mac Outlook say can't connect to microsoft exchange. Sending emails from Iphone and Ipad works fine but not from a mac laptop.
I replace the web.config with the old one but still no success even after restarting the server.
Trying to fix the attachments size problems I end up with a bigger problem.
Any suggestions on this other than telling them to buy a PC. I already suggest it. LoL

I find out that the ews does not work due to the fact than the maxallowedcontentlenght is more than 2 megs and 2 megs is the max.
Is there any other way to make this to send more than 2 megs.
I edit both ews and owa web.config and change the value to the maxallowed... to 60 megs then I run under the command prompt
c:\Windows\System32\inetsrv>appcmd set config "SBS Web Applications/ews" -section:requestFiltering -requestLimits.maxAllowedContentLength:60971520
and same for the owa then I restart IIS but once I do this no mac can even connect to exchange until I go back under the 2 megs

I thought this was similar to a problem I solved recently using and

The mistake I made was not making the changes across several attributes which work together in mysterious ways. If you think these don't offer anything new let me know and I'll keep digging
