Powershell: How to set “Out of the office” to a list of users.

Here is a script for setting an Out of the office (OOO) message to a list of users.
Tested on Exchange 2010.

First, careat a CSV file (OOOUsers.csv) with all the users in one column and put it in c:\ooo\.
Than, create a *.ps1 file and copy the script into it.
Save it in C:\ooo\.

# Location of the users CSV file
$OOOUserList = get-content -Path c:\ooo\OOOUsers.csv
# Set OOO start time
$OOOStart = '08/20/2015 00:00:01'
# Set OOO end time
$OOOEnd = '08/25/2015 23:59:59'

# Set the OOO InternalMessage
$InternalMsg = "I'm OOO for now.....<BR> Thanks."
# Set the OOO ExternalMessage
$ExternalMsg =  "I'm OOO for now....<BR> Thanks."

foreach ($item in $OOOUserList){
	write-host Creating OOO for: $item
	Set-MailboxAutoReplyConfiguration -Identity $item -AutoReplyState Scheduled -StartTime $OOOStart -EndTime $OOOEnd  -InternalMessage $InternalMsg -ExternalMessage $ExternalMsg
}

Now run the script…
