Outbound Email to customer is in a loop.

[Tim ONeal]

We have two tickets that were closed and the email address that the emails are being sent to has been delete by the end customer due to the employee being let go.
Now we are constantly getting an email (over 200 now) from Outlook Mail telling us the email is invalid.

Does anyone know how to correct this?

Regards,
Tim

Hello Tim, 

Thank you for reaching out to Atlassian Community!

Searching for blocks or bounces regarding your email domain, I found out only one bounce related to an email that I believe it's from the user you mentioned:

550: 550 5.4.1 ...@... Recipient address rejected: Access denied [SN1NAM01FT025.eop-nam01.prod.protection.outlook.com]

I removed this bounce, but it will probably happen again since the email doesn't exist anymore, but let's wait to see what happens.

Please, take your time and let us know if it fixed the issue.

Otherwise, if possible, your IT team could activate this email address again for the notification to be delivered and then delete it again. 

Regards,
Angélica
