Set Mailbox Auto Reply

Purpose: Sometimes you need to set an autoreply on a mailbox on behalf of someone else. In these cases, you can leverage the "Exchange Admin Shell" to configure an auto-reply to anyone who sends an email to the mailbox.

In the example below, replace <username> with the shortened username of the target user. (e.g. nicole.rappe not [email protected])

Set-MailboxAutoReplyConfiguration -Identity <username> -AutoReplyState Scheduled -StartTime "1/1/2025 00:00:00" -EndTime "1/15/2025 00:00:00" -InternalMessage "Example,<br><br>Message here.<br><br>Thank you." -ExternalMessage "Example,<br><br>Message here.<br><br>Thank you."

Internal vs External

When you configure auto-replies, you can have different replies sent to people within the same organization versus external senders, keep this in mind based on the roles of the person.

Example Email Reply

The email auto reply will look something like this based on the command above.
