How to add or change your signature in Outlook for Windows
When you have Outlook open, start a new email.

In the new email window, click on the Signature button, and select Signatures from the menu.

In the window that comes up, select New to create your new signature.

You’ll need to give your signature a name to refer to it by, since you can create multiple signatures. This signature is called Main, because it is the main signature this user will use. Click on OK when you’re done.

Once you have named the signature, you can use the main text box to type in exactly what you want your signature to say. There are controls for the typeface to be used, as well as to add pictures and/or links. When you have your signature how you like it, click on OK at the bottom of the window to save your signature.

Back in the new email window, clicking on the Signature button will show a new choice, Main. Click on Main to add the signature you just set up to your email. You can add as many signatures as you like, and choose among them when composing an email. And that’s it, you’re done adding a signature in Outlook.

To edit or delete an existing signature, go into the Signatures dialogue like you did to add a new signature.

In the dialogue box that comes up, select the Main signature.

Make your edits (in this case, a new title), and click on OK to save your changes. Your updated signature will be used when you click on Main in the Signature menu.

How to add or change your signature in the Outlook app
Open your Android Outlook app. Tap on your account image in the upper left.

From the menu, select Settings at the bottom left.

Signature will be a menu choice within Settings. Tap on it.

You will see that Signature is pre-populated with a stock signature for your phone model. Tap at the end of the signature to delete it so you can add your own.

When you have your signature the way you like it, tap on the check mark in the upper right to preserve your new signature.

To edit your signature, just follow this procedure again, and overwrite your old signature with your new one. You can edit your signature as often as is necessary, but keep in mind that the Outlook app restricts you to one signature, unlike the desktop program that allows you to have multiple signatures. You are now ready to employ signatures in your Outlook emails.
