I tried Exchange server rules but wasn’t pleased with the long default message. So if there is a way to edit this messageI’ll be happy to learn how.Thank you all.

Which message are you referring to?

Thank you AndyD, I can’t find the name of this message but it’s part of exchange server rules. The name is not important if you can help figure out how to auto reply to any message sent to a specific mailbox. Yes, I know I can create a rule or OutOfOffice but then it only reply once while done through the server it reply every with every incoming mail.

Can you post the text of the message that you're referring to?
