Powershell Script or GPO to Reset OOO message count on Exchange 2010

I am looking for an PowerShell script or GPO that will disable the Out Of Office assistant or OOO and then re-enable it to clear the message count to external senders for Exchange 2010. This would need to be done on the exchange server itself. Can anyone help?

Showing for two mailboxes:
"identity1", "identity2" |
  Get-MailboxAutoReplyConfiguration | 
  ? { $_.AutoReplyState -ne 'Disabled' } |
  % {
    $ooo =  $_
    $ooo | Set-MailboxAutoReplyConfiguration -AutoReplyState Disabled
    $ooo | Set-MailboxAutoReplyConfiguration -AutoReplayState $ooo.AutoReplyState -StartTime $ooo.StartTime -EndTime $ooo.EndTime

Open in new window

This can be changed easily to use get-mailbox instead of a list to go thru all mailboxes.

I just want to point out that to use that script with that cmdlet you will need to be running atleast Exchange 2010 SP3.

Thank you for the reply. Please clarify as to how I would use the above to disable all autoreply on the entire organisation iso per mailbox. I am not a expert on PowerShell and would prefer a gpo, but it seems like there is no such an option.

No, a GPO is not appliable. It always runs either for a machine or user, with that scope. The Exchange Server does not use GPOs.

Do you want to go thru all mailboxes, and if OOO is active trigger the state? Or do you need a more restrictive filter (particular OU, for example)?
If all mailboxes shall be processed, just replace line 1 with
Get-MailBox -ResultSize Unlimited |

Open in new window

otherwise you need to set up e.g. the filter parameter of that cmdlet to your needs. For details see https://technet.microsoft.com/en-us/library/bb123685(v=exchg.141).aspx.
