Changing your signature in Outlook is pretty straightforward! Typically, you'd go to 'File' > 'Options' > 'Mail' and find the 'Signatures' option. From there, you can create, edit, or select the signature you want to use. Have you been wanting to update your signature for a while, or is this for something specific? I'm curious about the style or information you'd like to include—it can be a fun form of personal expression!
