Sunday Morning: A user leaves a voicemail at 08:00. At 10:00 they email the Helpdesk and complain that the voicemail has not been addressed. The voicemail system will be unavailable, due to scheduled maintenance, from 08:00 - 12:00. You attempt to call the user, but they are working from home (we think) and the Helpdesk does not have contact details. Compose an email to the user that will address this issue.
