Change system generated Out of Office Prefix in Exchange Online

Hi all,

My customer wants to change the system generated prefix for out of office messages in Exchange Online. Is there a possibility to replace the OOF prefix "Automatic reply:[Subject]" with a custom message? For example "Automatic Out of Office Replay:[Subject]".

Kind Regards

Steve

    Not possible with the standard Out Of Office reply feature.

    You can create custom auto-replies with Outlook and not use the Out Of Office wizard, but you have to leave Outlook running:

    I believe you can create a Power Automate flow that will rewrite the prefix.

    Alternatively you can use a third-party cloud service to modify an OOF message.
