If you are running a SBS 2011 server, after upgrading Best Practices Analyzer (BPA) with UR3, you may see the following warning message:
The /EWS virtual directories maxRequestLength doesn’t match the get-transportconfig MaxSendSize
This warning is NOT applicable to SBS 2011, and should be ignored!
To ignore this warning and prevent it from showing up again in the future, simply click on the “Exclude this Result” button that is displayed in the BPA for this warning.
However, if you have already performed the resolution steps as recommended in the BPA, just repeat the steps and reset the maxRequestLength to 2097151 (which is 2GB).
