1. You can choose to auto insert your mail signature into a mail or insert it manually when required. Clicking on the Manage Signature button from either the ITEMS ribbon menu, or from within a mail form opens up a dialog box where you can configure your signature.
2. On the dialog box, you can enter or edit your signature and choose whether you want it to be included in all new mails and whether it needs to be included when you reply or forward a mail.
3. You can also manually insert your saved signature by clicking the Insert Signature button on the mail form.
Note: If you update a signature while a new mail is open, you will have to manually re-insert the updated signature.
