Hello, Im looking to make a custom NDR to replace the one for "552 5.3.4 Message size exceeds fixed maximum message size". I want to include what our limits are and some suggestions on how to reduce the emails size. We are running Exchange 2007 on 2008 Server. I cant seem to find anything to guide me though customizing it. Anyone able to help or point me in the right direction? Thanks! Things ive tried: Using the cmdlet New System Message to change DSN. Setting this command - Set-TransportConfig -DSNConversionMode DoNotConvert The Transport Rule wording seems to point to single attachments and not the size of the total email so im not sure that will work.

Hi vanir, Try below Cmdlets, New Custome messageNew-SystemMessage -QuotaMessageType "WarningMailbox" -Language EN -Text "Add your custome mailbox Werning" to see custome messageGet-SystemMessage -Identity EN\WarningMailbox | FL To Modify Custom Quota Messages Set-SystemMessage -Identity EN\WarningMailbox -Text "This is a modified custom quota message." To Remove Custom Quota Messages Remove-SystemMessage -Identity EN\WarningMailbox Resources========= How to Manage Quota Messages---------------------------------http://technet.microsoft.com/en-us/library/bb232089.aspx New-SystemMessagehttp://technet.microsoft.com/en-us/library/aa998878.aspx Regards

New-SystemMessage -QuotaMessageType "WarningMailbox" -Language EN -Text "Add your custome mailbox Werning" Isnt that command only for internal mailbox size messages? Im looking to set the message external senders get when sending an email with an attachment that's too large for our system. Would that command work for that?

HI,Please read below technet article it is mentioned good examples end of thr page New-SystemMessage http://technet.microsoft.com/en-us/library/aa998878.aspxRegardsChinthaka

I tried that, Here is the command i used: New-SystemMessage -DsnCode 5.3.4 -Text Your email is over the size limit of 15 MBs, Please try resending the email with fewer or smaller attachments. -Internal $false -Language EN But i still get this message when i send a large email: Subj: Big Email Sent: 2009-06-29 16:18 has encountered a delivery problem. Reason: Mailbox full The mailbox is full because the user has exceeded a per-mailbox administrative quota or physical capacity.

HI, sorry for the forgottenyou must restart Transport services use below CMDletsRestart-Service msexchangetransport -VerboseRegardsChinthaka

HI, sorry for the forgotten you must restart Transport services use below CMDlets Restart-Service msexchangetransport -Verbose Regards Chinthaka Will that kick anyone off the server? Also i found an oddity... I decided to check the SMTP logs to make sure that it was indeed Exchange that was bouncing the message and not GMail, our SPAM Filter, Or Firewall. The messages do seem to get to our Exchange server but this is what the SMTP logs show on our SPAM Filter: 09-06-30 12:57:50 0153: < 552 5.3.4 Message size exceeds fixed maximum message size 09-06-30 12:57:50 0153: Sending DSN (type failed) 5.2.2 (Mailbox full) to xxxxxxx@gmail.com If Exchange is giving a 5.3.4 error then why is it wanting to send a 5.2.2 DSN?

I restarted the service and tried it again and still get the same bounce. Subj: NDR Test 6 Sent: 2009-06-30 15:50 has encountered a delivery problem. Reason: Mailbox full The mailbox is full because the user has exceeded a per-mailbox administrative quota or physical capacity. Transcript of session: DATA 354 Start mail input; end with <CRLF>.<CRLF> 552 5.3.4 Message size exceeds fixed maximum message size

I still have a need to make a custom bounce back message so any help on this would be appreciated!

Why not create a transport rule at the Org level? 1. org\hub transport --> Transport Rules tab 2. New Transport rule 3. select "when the size of any attachment is greater than or equal to limit" and put in 16Mb or whatever you wish... 4. Next 5. select "send bounce message to sender with enhanced status code" and type in the customized message. (the limit is 128 char.) so I suggest something like this... "Delivery not authorized, message refused. This message is larger than the current 16Mb system limit. " 6. next and finish... 7. restart the transport service
