Known Issue in Windows Server Solutions BPA Update Rollup 3
After you update Windows Server Solutions BPA with UR3 and execute it on Small Business Server 2011 Standard, it displays a warning:
The /EWS virtual directories maxRequestLength doesn't match the get-transportconfig MaxSendSize
The checking logic of this rule is incorrect. If you modify the value as per the Resolution, it will impact most of the EWS consumers and some OWA scenarios also breaks.
As long as maxRequestLength is set to the default value ‘2097151’ (which is 2GB), it will be fine. The warning can be safely ignored on Small Business Server 2011 Standard servers.
