Collegue does not receive invitation Mail

Question

Dear all,

we invited several persons to Jira.

Unfortunately one person does not receive the invitation mail from our admin. We tried already a lot of things in Jira to fix it, but we cannot find the problem. Is the mailadress maybe blocked in your system? If so, is it possible to unblock it?
Can I write you here the name of the mailadress or is this an open chat where I should not post personal data?

Thanks a lot for your support.

Best,

Theresa Rausch (UBG)

Hi @Theresa Rausch welcome to the Atlassian Community!

Currently, when an Atlassian system sends an email to a user (due to a Cloud site invitation, Jira or Confluence notifications, any changes that would be notified via email) there is the possibility that the email will be bounced. When this happens the email address is marked with a bounce and all further emails are blocked. This mechanism is made to prevent Atlassian mail services from being marked as spam by other mail services but currently it is not possible for site/org admins to know when this happens, nor to clear the bounce on Atlassian side and it is required to contact Atlassian Support for this.
