How Can You Turn off an Out of Office Message for a User in Office 365
- 
 I have a user that set an OOO away message and then left for extended leave and we need to shut it off. I know we can reset her password and manage the account as her, but short of doing that, is there a way to turn it off from the O365 console or PowerShell or something? 
- 
 Can be done in the console. Pull up their profile in the Admin console, under Mail Settings, OOO should be right there. Edit: Its called "Automatic Replies".

 You can use Powershell as well Set-MailboxAutoReplyConfiguration -Identity username -AutoReplyState disabled
