This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again.

Mysteriously I am no longer able to send large email messages, because I get an NDR saying "This message is larger than the current system limit or the recipient's mailbox is full.  Create a shorter message body or remove attachments and try sending it again."

This is the same as described in a past questions that was resolved by a restart of the Server but this did not resolve my problem.

I have no restrictions set in any of the following places:

Global Settings > Message Delivery > Properties> Defaults
Protocols >Default SMTP Virtual Server > Properties > Messages
Connectors > Default SMTP Connector
Active Directory Users and Computers> User Properties

What is realy wierd is that this is a problem that has cropped up, when previously it was OK.

Can anyone suggest what the problem may be

"This message is larger than the current system limit or the recipient's mailbox is full.  Create a shorter message body or remove attachments and try sending it again." - did you checked the other end for the recipient's mailbox restrictions ?

Do you keep a change management form? The reason I ask this did you apply any patches or make any changes that lead to this. Keeping a change management form an be helpful in this regard.

Also as pointed out by ikm7176 check the setting of the recipient.
If you are forwarding all mail to your ISP who then delivers it for you, the ISP may have recently added restrictions.

You really need to check the NDR to see where it came from.  It could be either exchange/ISP or the recieving end.

Thanks everyone for your responses. I did not state the environnment : Windows 2003 native domain (All Sp1) and Exchange 2003 SP2

There are no restrictions on the recipients mailbox. I know this because I sent it to another site that I manage, and the recipient has no limit.

The NDR is being generated by my system. The ISP does not have any restrictions, I have confirmed this.

Yes I keep a Change Management Log, and there has been no changes to the exchange server to point to this problem.


kb 834384 seems to apply to Exchange 2000, so this seems not to fit
I am not running a x.400 connector so KB 811294 does not seem to fit
The recipient does not receive the message so KB327379 also does not fit
