552 5.3.4 Message size exceeds fixed maximum message size> #SMTP#

Posted on 2014-02-06
Last Modified: 2015-01-22
We have an Exchange 2010 server and we do not have any limits on sending and receiving for our users. We can typically receive email attachments up to 30 MB or so.

A user was informed by a client that an email attachment that was 25 MB was giving a 552 5.3.4 Message size exceeds fixed maximum message size> #SMTP# message.

Why would this intermittently happen as this user has since been able to receive emails higher than 25 MB? Any assistance offered would be greatly appreciated.

I would check your global settings or your send connector to see if there is a limit

That you recieve such big emails is probably due to office dsl where your clients isp could limit this to lower size.

You need to post the entire message to determine which generating server this truly came from.

"I would check your global settings or your send connector to see if there is a limit" I checked and there is no limit. I don't like that we send and receive such large email attachments but the powers that be wanted any limitation taken off.

This points to appriver, which I assume is hosting the sender's account. Their servers are generating this NDR.

Yes, this was from their servers. They sent us the message.

I'd suggest you to check the settings in these places:

1. Organization Configuration

Organization Configuration | Hub Transport | Global Settings tab | Transport Settings |

2. Server Configuration

Server Configuration | Hub Transport | select a HT server | Receive Connectors -> select a connector | Properties |

 3. Send Connector Configuration

Organization Configuration | Hub Transport | Send Connectors -> select connector | Properties |

 4. Recipients Configuration

Recipients Configuration | Mailbox | select mailbox | properties | Mail Flow Settings | Message Size Restrictions|

 5. Recipients Group Configuration

Recipients Configuration |Distribution Group | select Group | properties | Mail Flow Settings | Message Size Restrictions

 6. Transport Rules

Organization Configuration | Hub Transport | Transport Rules

Like i Saïd, your customers ISP is blocking it due lower size limits, very common behaviour.

So Pat, can you see where in the message that it the customer's ISP blocking it on their end? Just so I can point this out?

Here it all is. Probably your customers ISP is appriver.

I also recently ran into this situation and it turned out to be my receive connectors.  My receive connectors also have bindings to port 25. I have 8 receive connectors and only had the default one set to a file size larger than 10MB.  Once I identified which connectors were bound to port 25 using Power Shell command:   get-receiveconnector -identity "receive connector name here" | fl            ,I changed the attachment file size limit and verified the max file size, again using the PS command above and then my test file, which was previously rejected, came through successfully.  I hope this helps someone else.
