This policy setting allows you to set a deadline by when updates to Office must be applied.
Prior to the deadline, users will receive multiple reminders to install the updates. If Office isn't updated by the deadline, the updates are applied automatically. If any Office programs are open, they'll be closed, which might result in data loss.
We recommend that you set the deadline at least a week in the future to allow users time to install the updates.
If you enable this policy setting, you set the deadline in the format of MM/DD/YYYY HH:MM in Coordinated Universal Time (UTC). For example, 05/14/2016 17:00. To set the deadline in the device's local time add "Local" to the end of the deadline. For example, 05/14/2016 17:00 Local.
If you disable or don't configure this policy setting, no deadline is set, unless you specify one by using the Office Deployment Tool.
You can use this policy setting with the Target Version policy setting to ensure that Office is updated to a particular version by a particular date.
The deadline only applies to one set of updates. If you want to ensure that Office is always up-to-date, you need to update the deadline in this policy setting every time a new update for Office is available.
Important: This policy setting only applies to Office products that are installed by using Click-to-Run. It doesn't apply to Office products that use Windows Installer (MSI).
