under Edit Users it is possible to see the quota and usage. Is there a way to display a view for all domains/users in order to see which mailboxes may have already reached the limit? In this way, customers could be informed in good time and it would be avoided that a support ticket is opened for this reason, in which we then have to look and inform quota reached.
i have found the feature “Disk Quota Monitoring” in the pro edition
i think this solved my problem
