Logic app workflow failure

Question

Hello team,

Our workflow having Multiple SMTP connectors to handle 429 errors. basically , if there is a failure in a connector redirection is based on status code to next SMTP connector.

The above logic helped us in achieve functionally but we notice any one failure of SMTP indicates the entire workflow as failure and that not the real case because it is getting successful in another SMTP connector. we want to make the workflow to success if any of the SMTP connector get successful. Let us know on that and attached a screen shot for your reference.

Hi @Sriraghavendran Prabhakaran Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

The TooManyRequests warning you see indicates that you are hitting a throttling limit for the Connector. Assuming that you are using SMTP connector, I would like to point that there is a throttling limit of 100 calls that can be made per connection within a span of 60 seconds. It means that if your workflow sent 100 emails in a second, it would continue to face the TooManyRequests for the next 59 seconds. The same error would get cascaded down to other Send Email Actions within that time frame. Please refer the Throttling Limits documentation for reference.

If you have the requirement to send emails over the throttling limit, you may consider using different SMTP connections in the Logic App as the limits apply per connection.

Hope this answers your question.
