Email delivery fails [{LRT=};{LED=550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient};{FQDN=};{IP=}]

Hi All,

 We seem to encounter email delivery issue when the email is more thatn 35+ MB. Exchange 2013 with MBX/CAS and Edge servers.

On the Mailbox
C:\>get-transportconfig
MaxReceiveSize                                              : 25 MB (26,214,400 bytes)
MaxSendSize                                                 : 100 MB (104,857,600 bytes)

C:\>get-receiveconnector | ft name, maxmessagesize
All connectors including default are set to 100 MB

C:\>get-sendconnector | ft name, maxmessagesize
All connectors including edge sync are set to 100MB

On the edge server

C:\>get-transportconfig
MaxReceiveSize                                              : unlimited
MaxSendSize                                                 : 100 MB (104,857,600 bytes)

C:\>get-receiveconnector | ft name, maxmessagesize
All connectors including default are set to 100 MB

C:\>get-sendconnector | ft name, maxmessagesize
All connectors including edge sync are set to 100MB

The entire transport pipeline has been configured with 100 MB max size, but the email more than 35+ MB fails to deliver
