Outbound emails are failing to send with "Send Status Failed". - Connect IT Community | Kaseya
<main> <article class="userContent"> <p><strong>Problem:</strong> Email responses to be sent for the Customers from assigned workflows are failing - manual notification emails are sent successfully. Upon checking "Admin > Logs > Outbound email logs" we see that the send is failing and the "Email History"<strong> </strong>tab has the below error: </p> <p><em>Failed Mailbox unavailable. The server response was: 5.7.60 SMTP; Client does not have permissions to send as this sender [xxxx.prod.outlook.com]</em></p> <p><img src="https://us.v-cdn.net/6032361/uploads/migrated/Q0ZCSLKODZQZ/mceclip0.png" alt="image" class="embedImage-img importedEmbed-img"></img></p> <p><strong>Cause: </strong>The email address used in the email template of the workflows does not have permissions to send on behalf. This error is seen when Office 365 works with unknown emails.</p> <p><strong>Solution: </strong>Follow these steps:</p> <p><strong>1.</strong> Check the email template associated with the workflow. </p> <p><strong>2.</strong> Edit the email address in the email template of the workflow. Make sure the sender mail address matches the domain handled by your SMTP server:</p> <p><img src="https://us.v-cdn.net/6032361/uploads/migrated/IBTYRV03VR7G/mceclip1.png" alt="image" class="embedImage-img importedEmbed-img"></img></p> <p><strong>3.</strong> Save the changes and check if the emails are now sent successfully. </p> <p> </p> <p><strong>Applies to</strong>: O365 Mail Servers used in BMS.</p> </article> </main>
