- Numeric Code: 5.5.3 Possible Cause: Too many recipients on the sent <br>message. Troubleshooting: The recipient limit is a configurable limit <br>on the receiving server. To resolve this issue, either increase the <br>recipient limit, or break up the message into multiple messages to fit <br>the server limit. Note The default recipient limit on a Simple Mail <br>Transfer Protocol (SMTP) message is 5000. To set this limit, start the <br>Exchange System Manager, click the Global Settings node, right-click <br>Message Delivery, and then click Properties. This can also be a <br>per-user setting in the Active Directory.
