How do I know if I have New Outlook or classic Outlook?

New Outlook has a simplified interface that looks like a web app. Classic Outlook has a traditional ribbon with File, Home, Send/Receive, Folder, and View tabs. They have different signature settings.

Does New Outlook support HTML signatures?

Partially. New Outlook supports basic HTML but strips many CSS properties. Use simple, table-based signatures without custom fonts or complex layouts.

Can I switch back to classic Outlook?

Yes. In New Outlook, look for the toggle in the top-right that says 'Go back to classic Outlook'. This may vary by your Microsoft 365 subscription.

Do my signatures sync between New Outlook and Outlook web?

Yes — New Outlook stores signatures in your Microsoft account, so they sync with Outlook web (outlook.com or outlook.office.com).

How to Add an Email Signature in New Outlook (Windows)

Microsoft released a redesigned Outlook app for Windows in 2024 with a new interface and a different settings structure. If your Outlook looks like a web browser tab with a simplified ribbon, you're using New Outlook. Here's how to add your signature.

Before you start

You'll need a signature to paste. Already have one? Skip to step 1.

Step-by-step setup

Open the New Outlook app. Click the gear icon in the top-right corner of the window to open the Settings panel.

In the Settings panel, click "Accounts" in the left sidebar.

Under Accounts, click "Signatures". You'll see an option to create and manage signatures.

Click "New signature". Give your signature a name.

In DropSig, click "Copy Signature" to copy your formatted signature.

Click in the signature editing area and paste (Ctrl+V). Note that New Outlook has more limited HTML rendering than Outlook desktop — keep your design simple for best results.

Pro tip: New Outlook's signature editor is closer to the web version. Avoid complex CSS. Simple text + logo + links work best.

Use the dropdowns to set your signature as the default for new emails and replies. Click Save.

Common issues

Can't find the Signatures option

Make sure you're using New Outlook (not the classic desktop app). If you see a traditional ribbon with File/Home/Send/Receive tabs, you're in classic Outlook — see our Outlook 365 guide instead.

Formatting looks broken in New Outlook

New Outlook has limited HTML support. Stick to basic formatting: no custom fonts, no background colors. Use one of DropSig's simpler templates for this client.

Signature not saving

Make sure you click Save after editing. New Outlook occasionally requires a restart to apply signature changes — close and reopen the app if the signature doesn't appear.
