Meldung vom Exchange bei SBS 2011

Hallo,
ich nutze einen SBS 2011.
Jetzt bekomme ich über MBCA folgende Meldungen:

Issue: One or more receive connectors have a MaxMessageSize value that does not match the get-transportconfig MaxReceiveSize value.
Impact: Setting an incorrect or inconsistent MaxMessageSize value can cause email delivery failures.
Resolution: You can use the get-receiveconnector | ft name, maxmessagesize command to determine the maxmessagesize value and the names of the different connectors. You can then use the get-transportconfig | ft maxreceivesize command for comparison. For more information about how to change size limits, see the SBS Team Blog article, "How Do I Change Message Size Limits in SBS 2008/2011 Standard?" at http://blogs.technet.com/b/sbs/archive/2008/10/28/how-do-i-change-messa ... .

Issue: The Internet Information Services (IIS) virtual directory for EWS has a maxRequestLength value that does not match the get-transportconfig MaxSendSize value.
Impact: Setting an incorrect or inconsistent MaxRequestLength value can cause email delivery failures or an HTTP 404 error in OWA. Additionally, users may not be able to use OWA to send as large a message as they can send by using the Outlook client itself.
Resolution:
1. Find the Web.config file on the Client Access server. The default location is C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\exchweb\ews.
2. Make a backup copy of the web.config file.
3. Start the Exchange Management Shell and use powershell "get-transportconfig | ft MaxSendSize" to get the global max Send size, for example, 20M.
4. Find the maxRequestLength value, and change it to the value that you want. The value is in Bytes. The maxRequestLength value in the Web.config file: <httpRuntime maxRequestLength="2097151" />. Make this value match the one from get-transportconfig command line.
5. Save and close the web.conifg file.

hier die beiden o.g. Befehle. Was genau muss ich damit machen bzw. ändern?

get-receiveconnector | ft name, maxmessagesize

Default SBS-SERVER 100 MB (104,857,600 bytes)
Windows SBS Fax Sharepoint Receive SBS-SERVER 100 MB (104,857,600 bytes)
Windows SBS Internet Receive SBS-SERVER 100 MB (104,857,600 bytes)


get-transportconfig | ft maxreceivesize

das habe ich gemacht. die web.config hat "maxRequestLength="2047868928"" und "get-transportconfig | ft MaxSendSize" hat genau die gleiche Größe.


Bin für jeden Tipp dankbar.
