What’s happening?
The customer is experiencing an "Internal Server Error" when attempting to use certain functionalities, particularly related to email sending through the Mail connector.
Reason:
The errors encountered were caused by a misconfiguration on the service provider's end, which has since been resolved.
Resolution:
- Ensure all required fields in the email actions are present and valid.
- If using dynamic values for the fields, check the raw outputs of the previous action or the raw inputs of the "Send Email" action in the failed run to ensure valid values are present.
- One common error occurs when the "To" field is provided as an array from a dynamic value, which is not supported. The error message may indicate that the input parameter 'emailMessage/To' is required to be of type 'String/email'.
- If encountering an "invalid email" or "exceeded email service quota" error, ensure that the email addresses in the required fields are valid and check if the mailbox quota has been exceeded. Contact the Exchange administrator if necessary.
- If using the Mail connector to send email notifications, it is recommended to switch to the Office 365 Outlook connector's "Send an Email (V2)" action for the same purpose. If issues persist, review the limitations of the connector.
- If receiving a large number of automated emails or notifications, verify if there are any active flows in the Power Automate "My Flows" or "Shared Flows" sections. Additionally, inspect the internet mail headers for flow details.
