Attachment sizes on Emails. I am having a problem with the size of email which my users are allowed to send and receive.

I was asked by one of my users to increase the size of emails they are allowed to receive as some external senders were receiving bounce backs messages.
In the exchange management console I edited the transport setting found in the Organization configuration-à Hub transport.
I increased both the send and receive size to 30240kb

After making these changes one user received the following message when they tried to attach a document to an email.

The file were not attached because they exceed the maximum size limit of 10mb for attachments.
I believe external parties were still having problems sending large emails

Any suggestions to increase email send and receive sizes?

    From the Exchange console:

    for message size receive limits: Set-Transportconfig maxreceivesize
    for message size send limits: Set-Transportconfig maxsendsize

    Other places to look are Connector limits, server limits, and user limits.

    This is error which appears in the rejection bounce back message....

    #550 5.3.4 ROUTING.SizeLimit; message size exceeds fixed maximum size for route ##

    I googled the #550 5.3.4 ROUTING.SizeLimit and found another person who had the same problem and how they got around it.

    They used the below commands for the Exchange management shell

    Check your Send Connector:
    Get-SendConnector | Select identity,MaxMessageSize

    followed by increasing it's size:
    Set-SendConnector -identity "Name" -MaxMessageSize: 30MB

    When I check my connector I got the message back that my Mail Message Size for outbound email was 10MB

    When I try and run the below code to set my out bound email to 30MB

    Set-SendConnector -identity "daniel.buggy" -MaxMessageSize: 30MB

    I get this message....

    Set-sendConnector : The operation could not be performed because object 'daniel buggy' could not be found on domain controller 'serv-01.domain.nah'.
    At line:1 char:18
    + Set-SendConnector <<<< -identity "daniel buggy -MaxMessageSize: 30mb

    Can anyone tell me where I am going wrong with this command prompt? Or it there a way of changing this mail box size on the Exchange management Console

    Accepted Solution

    in the gui.

    Right click on user, properties, mail flow settings, message size restrictions.

    Too many email signature changes to deal with?

    Are you constantly being asked to update your organization's email signatures? Do they take up too much of your time? Wouldn't you love to be able to manage all signatures from one central location, easily design them and deploy them quickly to users. Well, you can!
