The internal e-mails can link directly to any document in the system and automatically generate messages for resubmission (see also contact system) or reminders for appointments (see also Team-Calendar).

The mail system can also be directly opened through the navigation bar. If there are no new (unread) incoming e-mails, the mailer is displayed with the button and otherwise displayed with the button. In the example, there are unread e-mails in the mail system and after clicking the button, the mailer is opened with the newest unread message in the inbox folder.

Using the e-mail can be set to resubmit. In the dialog, resubmit can be set to minutes, hours or days, as well as an absolute date element.
