Hello 

Have tried using the Set commands to set these limits using power shell.

Setting Message Size Limits in Exchange 2010 and Exchange 2007

1) Organizational limits:

Set-TransportConfig -MaxReceiveSize 50MB -MaxSendSize 50MB

2) Receive Connector limit:

Set-ReceiveConnector CONNECTOR NAME -MaxMessageSize 50Mb

3) Send Connector limit:

Set-SendConnector CONNECTOR NAME -MaxMessageSize 50Mb

4) Mailbox limit:

Set-Mailbox User A -MaxSendSize 50Mb -MaxReceiveSize 50Mb

It will fix the issue.

[Note: In Internet most of the Domain doesnt except more than 10 MB mail.]

Also if you are using Hybrid O365 and exchange environment, limit need to be carefully setup.

Hi Yasser,

According to your description , it seems that all send limitations are normal in your organization.

So, I think the issue you are encountering is that you can not send to External organization, right?

If yes, I recommend you tried to send the same message to other organizations(like gmail, outlook.com) and check if there is the same issue.

You need to contact the receive organization's administrator also, and confirm if the receive organization's restriction cause the issue.

Best regards,
