Why can't I just use a local signature file with the new Outlook?
The new Outlook stores signatures in the cloud and syncs them with your mailbox, unlike the classic desktop version. This means any local signature file gets overwritten when your account syncs — you have to add your signature directly through the in-app editor instead.
How do I add my email signature to the new Outlook for Windows and Web?
Click the Settings gear icon in the upper-right corner, then go to Accounts > Signatures.
Click New signature.
Copy your signature from the preview shown after saving it on htmlsig.com, then paste it into the editor box in Outlook.
Review your pasted signature — images, fonts, or hyperlinks can sometimes fail to copy correctly. Fix any spacing issues and re-add anything that didn't transfer.
Optionally, set this signature as your default so it's added to new emails automatically.
Click Save.
