Delete an Email Signature in Microsoft 365 (Outlook Web, Outlook Desktop)

Email signatures are an important element within business communications. That’s something that we are always highlighting on this site. A signature provides a business with a platform on which to give useful information to recipients of the email. That information can be your address, your social media handles, your address and other personal information about the person sending the email. Having an email signature adds credibility to your correspondences. However, a time may come when you need to delete one or more of your email signatures. Perhaps you have moved on to another company, or maybe you have come up with a new signature.
