Out of Office
This one is pretty straightforward—user’s gone from work unexpectedly and you need to set their out of office reply without resetting their password or granting yourself access rights to their account. The script is here:
Set-MailboxAutoReplyConfiguration -Identity domainuser -AutoReplyState Scheduled \
-StartTime "3/20/2018 08:00:00" -EndTime "3/22/2018 08:00:00" \
-InternalMessage "Hello, I'm out of the office on unplanned leave, if you need immediate assistance please contact $Supervisor at SupEmail@domain.name, thank you!" \
-ExternalMessage "Hello, I'm out of the office on unplanned leave, if you need immediate assistance please contact $Supervisor, thank you!" \
-ExternalAudience Known
The command makes use of the Set-MailboxAutoReplyConfiguration cmdlet in powershell. This is mirrored by the Get-MailboxAutoReplyConfiguration cmdlet which will tell you what’s currently set.
