  Too Mant Recipients  
This message wasn’t delivered to anyone because there are too many recipients, the limit is {number}. This message has {number} recipients
 

To check what the limit is set to launch the Exchange Management Shell, and ecxecute the following command;

 
Get-TranportConfig
  Get-Tranportconfig  

To raise the limit (in this example to 2000) use the following command;

 
Set-TranportConfig -MaxRecipientEnvelopeLimit 2000
  MaxRecipientEnvelopeLimit
