Set-MailboxAutoReplyConfiguration

Set-MailboxAutoReplyConfiguration

In many cases it’s very useful to have an autoreply on mailboxes. Maybe during user vacation or when on leave. Or maybe you want a shared mailbox to immediately notify customers that a message was received.

This post will show you how to configure an auto-reply for mailboxes using the Set-MailboxAutoReplyConfiguration PowerShell cmdlet. The command can be used against both on-premises and Office 365 mailboxes.

In the last section we’ll look at how to configure a mailbox autoreply using the Exchange Admin Center (EAC).

Mailbox Auto-Reply Using PowerShell

Use the Set-MailboxAutoReplyConfiguration command to set an auto-reply on your Office 365 mailbox. The below example shows you how:

Connect-ExchangeOnline
$InternMsg = "I'm out of office, please reach out to Tycho Brahe during my absence"
$ExternMsg = "I'm out of office, please contact tech@observatory.dk during my absence"
Set-MailboxAutoReplyConfiguration -Identity ole.roemer -AutoReplyState Enabled -InternalMessage $InternMsg -ExternalMessage $ExternMsg
Disconnect-ExchangeOnline

Start by establishing a connection with Exchange Online (line 1 – 3).

Define messages to internal and external senders (line 4 – 5).

Set the auto-reply using the Set-MailboxAutoReplyConfiguration command (line 6).

End your Exchange Online session when done (line 7). If you don’t explicitly close the session you risk depleting the number of available sessions.

Instead of enabling the auto-reply right away you can also schedule it by setting the AutoReplyState parameter to scheduled. You must then also supply parameters -StartTime and -EndTime.

To verify the auto-reply has been configured use the Get-MailboxAutoReplyConfiguration cmdlet:

PS C:\> Get-MailboxAutoReplyConfiguration -Identity ole.roemer
RunspaceId                       : f07d909f-7622-440c-8fcd-9f0bbc6b58d8
AutoDeclineFutureRequestsWhenOOF : False
AutoReplyState                   : Enabled
CreateOOFEvent                   : False
DeclineAllEventsForScheduledOOF  : False
DeclineEventsForScheduledOOF     : False
EventsToDeleteIDs                :
EndTime                          : 3/9/2020 1:00:00 PM
ExternalAudience                 : All
ExternalMessage                  : <html>
                                   <body>
                                   I'm out of office, please contact tech@observatory.dk during my absence
                                   </body>
                                   </html>
InternalMessage                  : <html>
                                   <body>
                                   I'm out of office, please reach out to Tycho Brahe during my absence
                                   </body>
                                   </html>
DeclineMeetingMessage            :
OOFEventSubject                  :
StartTime                        : 3/8/2020 1:00:00 PM
Recipients                       :
ReminderMinutesBeforeStart       : 0
ReminderMessage                  :
MailboxOwnerId                   : Ole Roemer
Identity                         : Ole Roemer
IsValid                          : True
ObjectState                      : Unchanged

As you may notice, by default the auto-reply is set to expire 24 hours after being activated. You can change this default expiration by setting the AutoReplyState to scheduled and supplying an expiration with the -EndTime parameter.
