ActiveSync - increase UploadReadAhead

Modify the web.config file under the Microsoft-Server-ActiveSync site in IIS for all CAS server. This modification changes the following:
MaxDocumentDataSize = 51200000
maxRequestLength = 51200

Then, in the command prompt, as an Administrator:

C:\Windows\System32\inetsrv
appcmd.exe set config -section:system.webServer/serverRuntime /uploadReadAheadSize:"10485760" /commit:apphost

Open the Default Web Site in IIS and select "Advance Settings"
Expand Connection Limits and increase the value to "240"
Then: iisreset
And -> IIS Manager - Application Pools - DefaultAppPool - select "Recycle" - the same with MSExchangeSyncAppPool.
This will increase the default limits in exchange for email size using ActiveSync (not recommended bigger than this)
