My boss asked me if there's a way to create a message of the day in Outlook 2010 that all users would see in their Outlook. We want to use this for the purpose of emergency alerts, i.e. hurricane warning, etc. We know we can send an e-mail, but there's no way to guarantee that message will be prominently displayed when the user opens their mailbox.
I saw a suggestion online about using group policy to configure Outlook today, unfortunately we support many workstations that are connected to Exchange but not members of the Active Directory domain.
Any other way to do this?
