SharePoint 2013 Maintenance Notification

Introduction

SharePoint 2013 contains a SPMaintenaceWindow class which can be used to give notifications to end users scoped to SharePoint content database. This is a simple PowerShell script you need to execute.

Example

Enable Notification

$maintenanceStartDate  = 
   "11/29/2013 08:00:00 AM" # Date when the maintenance will start
maintenanceEndDate    = 
   "11/30/2013 02:00:00 PM" # Date when the maintenance will stop
$notificationStartDate = 
   "11/28/2013 06:00:00 AM" # Date when the message will start being displayed
notificationEndDate   = 
   "11/30/2013 02:00:00 PM" # Date when the message will stop being displayed
$maintenanceLink       = 
   ""                      # This link will only appear if the maintenance duration is defined.
maintenanceType       = 
   "MaintenancePlanned"    # OPTIONS ARE: MaintenancePlanned | MaintenanceWarning
$readOnlyDays          = 1   # duration days
readOnlyHours         = 6   # duration hours. 
$readOnlyMinutes       = 0   # duration minutes only appears if days and minutes are both zero
 
$maintenanceWindow = New-Object Microsoft.SharePoint.Administration.SPMaintenanceWindow
maintenanceWindow.MaintenanceEndDate    = $maintenanceEndDate
$maintenanceWindow.MaintenanceStartDate  = $maintenanceStartDate
maintenanceWindow.NotificationEndDate   = $notificationEndDate
$maintenanceWindow.NotificationStartDate = $notificationStartDate
maintenanceWindow.MaintenanceType       = $maintenanceType
$maintenanceWindow.Duration              = 
	New-Object System.TimeSpan( $readOnlyDays, $readOnlyHours, $readOnlyMinutes, 0)
maintenanceWindow.MaintenanceLink       = $maintenanceLink
 
Get-SPContentDatabase | % {
    $_.MaintenanceWindows.Clear()
    $_.MaintenanceWindows.Add($maintenanceWindow)
    $_.Update()
}

Disable Notification

Get-SPContentDatabase | % {
    $_.MaintenanceWindows.Clear()
    $_.MaintenanceWindows.Add($maintenanceWindow)
    $_.Update()
