Since the update of confluence and switch to the use of email addresses, we are having the following problem with Confluence:
When we created a new user, the user doesn't receive the activation mail.
The email address isn't an alias (already checked).
Strange enough, when I sign-in as the user as admin, it is possible and the user does receive the "warning:your Atlassian Cloud administrator has logged in as you" mail.
When I reset the password, the user again doesn't receive the "reset password" mail.
