I am unable to send or receivemsgs larger than 10MB. The exact error is: 5.3.4 ROUTING.SizeLimit; message size exceeds fixed maximum size for route I have looked at the following and made the server level changes: http://technet.microsoft.com/en-us/library/bb124345.aspx http://technet.microsoft.com/en-us/library/bb310771.aspx From these posts I believe that the problem is on the recieve and send connectors: http://forums.msexchange.org/m_1800436085/printable.htmhttp://forums.msexchange.org/m_1800436085/printable.htm http://blog.justinho.com/SyndicationService.asmx/GetRssCategory?categoryName=Exchange%202007 http://203.222.76.198/Microsoft.htm I have made the changes using AdsiEdit, however the connectors still show 10MB limits: [PS] C:\Documents and Settings\Administrator.XYZ>get-receiveconnector | fl max* MaxInboundConnection : 5000MaxInboundConnectionPerSource : unlimitedMaxInboundConnectionPercentagePerSource : 100MaxHeaderSize : 64KBMaxHopCount : 30MaxLocalHopCount : 3MaxLogonFailures : 3MaxMessageSize : 10MBMaxProtocolErrors : 5MaxRecipientsPerMessage : 5000 MaxInboundConnection : 5000MaxInboundConnectionPerSource : 100MaxInboundConnectionPercentagePerSource : 2MaxHeaderSize : 64KBMaxHopCount : 30MaxLocalHopCount : 3MaxLogonFailures : 3MaxMessageSize : 10MBMaxProtocolErrors : 5MaxRecipientsPerMessage : 200 In trying to set the maxMessageSize I receive the following error, however I don't see what is wrong with my syntax. [PS] C:\Documents and Settings\Administrator.XYZ>set-receiveconnector -Identity"Client Main-ExchServ1" maxmessagesize 25MBSet-ReceiveConnector : A parameter cannot be found that matches parameter name'maxmessagesize'.At line:1 char:21+ set-receiveconnector <<<< -Identity "Client Main-ExchServ1" maxmessagesize 25MB Ideas are appreciated. Nice job MS, releasing a product that requires editing the AD to change the message size limits, this wasn't released half baked.....

Hi, Have you tried this command: set-receiveconnector -Identity "Client Main-ExchServ1" -maxmessagesize 25MB Leif
