Hi all,
My environment : Exchange server 2013 CU19 , Windows server 2008 R2
The message size limit is 20MB, now I want to increase incoming message size limit to 25MB
[PS] C:\Windows\system32>Get-ReceiveConnector | Format-Table Name,Max*Size,MaxRecipientsPerMessage; Get-SendConnector | Format-Table Name,MaxMessageSize; Get-AdSiteLink | Format-Table Name,MaxMessageSize; Get-DeliveryAgentConnector | Format -Table Name,MaxMessageSize; Get-ForeignConnector | Format-Table Name,MaxMessageSize Name MaxHeaderSize MaxMessageSize MaxRecipientsPerMessage ---- ------------- -------------- ----------------------- Default server2 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 5000 Client Proxy server2 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Default Frontend server2 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Outbound Proxy Frontend ID... 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Client Frontend server2 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 internal relay 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Default server1 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 5000 Client Proxy server1 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Default Frontend server1 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Outbound Proxy Frontend ID... 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Client Frontend server1 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 internal relay 128 KB (131,072 bytes) 25 MB (26,214,400 bytes) 200 Name MaxMessageSize ---- -------------- To Internet ( this is send connector) 20 MB (20,971,520 bytes) fortimail (disabled) 10 MB (10,485,760 bytes) Name MaxMessageSize ---- -------------- DEFAULTIPSITELINK Unlimited Name MaxMessageSize ---- -------------- Text Messaging Delivery Agent Connector Unlimited [PS] C:\Windows\system32>get-transportconfig | ft maxsendsize, maxreceivesize MaxSendSize MaxReceiveSize ----------- -------------- 25 MB (26,214,400 bytes) 25 MB (26,214,400 bytes)
I have restarted Microsoft Exchange Transport service (2 servers) and waited for over 2 hours but incoming messages larger than 20MB still are rejected
Delivery has failed to these recipients or groups:
myuser@mydomain.com
The recipient won't be able to receive this message because it's too large.
The maximum message size that's allowed is 20 MB. This message is 23 MB.
Do I have to restart my exchange servers to make it works ?
