Hi All, In Exchange 2007Is there a way you can setup to notify a userwhen they exceeds the message limit (attachment) while sending the email or after sending the email. I am NOT talking about mailboxquota limit. Thanks in advance.

You can alway use the set-mailbox <identity> -maxsendsize <sizelimit> ex. 10MB Sr. Exchange Engineer - Constellation Energy

I am not asking about how to limit the message size. All i need to know a notification to user/s once they tried to send a message more than the specified size. Thanks

Limiting the send size limit will notify the user that the message was too large. I guess I am not understanding exactly what you want. So you want to notify the user they exceeded the size limit but still allow them to send the message?Sr. Exchange Engineer - Constellation Energy

Issue description: How to set up a notification to users when they send the messages that exceeds the message limitation? By default, if a user sends an oversize message, the message will stuck in the Outbox folder, and an error mark will display in the right below corner, when the user click on it, an explanation would show: 0x80040610 "the message size being sent exceeds the message size established for this user" But I assume that youve already known the info above, and you want to provide more obvious notification for users, like a message, right? If so, you just need to increase MaxSendSize for attachment limitation on the global setting, but keep MaxReceiveSize as default, like 10MB If user send the message which message size being sent exceeds 10 MB to other users in the org, he (she) will receive the NDR like below: ============== Delivery has failed to these recipients or distribution lists: jamesluo@sg.com This message exceeds the maximum message size allowed. Microsoft Exchange will not try to redeliver this message for you. Please make the message smaller -- by removing attachments, for example -- and try sending it again, or provide the following diagnostic text to your system administrator. #550 5.2.3 RESOLVER.RST.RecipSizeLimit; message too large for this recipient ## ============== And if user sends oversized messages externally, he (she) will receive the NDR like below: ============== Delivery has failed to these recipients or distribution lists: jamesluo@external.com This message exceeds the maximum message size allowed. Microsoft Exchange will not try to redeliver this message for you. Please make the message smaller -- by removing attachments, for example -- and try sending it again, or provide the following diagnostic text to your system administrator. #550 5.3.4 ROUTING.SizeLimit; message size exceeds fixed maximum size for route ## ============== How to increase the MaxReceiveSize: a. Set-TransportConfig -MaxSendSize 500MB b. Restarted the Transport Service and the IS Service to clear the store cache

To Aaron.Yes.To james. Thanks. I know all these solution.But anyway thanks to all. I guess that is not possible what I was looking.

So, you want to allow users to send large messages but also reply a warning message I think you can create a mailbox like Oversize Alert, and then create a transport rule on the hub, CC all the large messages to Oversize Alert. Later, launch outlook for Oversize Alert and set a server-side rule to reply a warning template to users, say Your message is oversized and the like Transport rule: When the size of any attachment is greater than or equal to xxx Copy the message to Oversize Alert Create a warning template: a. Create reply message (text and subject) in a new message window b. File menu->Save As to save it as an .oft template file Server-side rule: Apply this rule after the message arrives Where my name is in the CC box Reply using template file Notes: To keep the mailbox size, you can also set a second rule on Oversize Alert to delete those received mail under the warning reply rule Notes: Anyway, I still think you should set a limited size which cant be allow under any circumstance
