​
​Step 6.
Paste your signature into the signature section using the keyboard combination CTRL + V (for Windows) or Cmd + V (for Mac).
​
​Note: Please put the tick in two options to ensure your signature will show up in your composed/forwarded/replied emails, and choose HTML format for writing new messages.

Note: If you paste your signature directly into a new email (for example, to send it to a user with your own instruction), please make sure you choose the paste option "Keep source formatting."
​

Step 7.
​Save changes by clicking Save button. Then, close the settings window.

Step 8.
​Compose a new email and see what the signature looks like there.

Viola! Now, your Outlook.com email signature will appear in every new email, reply, or forward message you compose.
