Outlook Choose default signature

On the Message menu, select Signature > Signatures.

Depending on the size of your Outlook window and whether you’re composing a new email message or a reply or forward, the Message menu and the Signature button might be in two different locations.

Under Choose default signature, set the following options for your signature:

In the E-mail account drop-down box, choose an email account to associate with the signature. You can have different signatures for each email account.

If you want your signature added to all new messages by default, in the New messages drop-down box, select one of your signatures. If you don’t want to automatically add a signature to new messages, choose (none). This doesn’t add a signature to any messages you reply to or forward.

If you want your signature to appear in the messages you reply to and forward, in the  Replies/forwards drop-down, select one of your signatures. Otherwise, accept the default option of (none).
