Not receiving any notifications when issue is created

[Jason Yeung]

Hi,

I've setup a shared mailbox in Office 365 that would be used for customers to submit issues. The email address in email settings is set to this mailbox and so far, the issues are created successfully when emails are sent to this mailbox. However it's not sending notifications back. 

I checked the outgoing mail logs and got the following error:

com.atlassian.mail.MailException: com.sun.mail.smtp.SMTPSendFailedException: 554 5.2.252 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message

I did some invesigation and this link mentioned I may need to set “Send email on behalf of another user":

I had a look on how the mailbox is set and it turns out that this mailbox doesn't have an Exchange Online license applied. I was wondering do I need to get Exchange for this mailbox?

Sincerely,

Jason

@Jason Yeung The mailbox has to be a fully functional exchange mailbox or it can not send email.  License the account and emails should start flowing.
