What's the difference between Outlook.com and Outlook web?

Outlook.com is Microsoft's free personal email (outlook.com, hotmail.com, live.com). Outlook web refers to the browser version of Microsoft 365 business email (outlook.office.com). The interface is similar but the accounts are different.

Does Outlook.com support HTML signatures?

Yes. Outlook.com supports HTML signatures with images and links. Complex CSS may be stripped, but table-based layouts like DropSig templates work well.

Can I have multiple signatures in Outlook.com?

Yes. In Settings → Mail → Compose and reply, you can create multiple signatures. Use the signature dropdown in the compose window to switch between them.

Step-by-step setup

Go to outlook.com and sign in to your Microsoft account.

Click the gear icon in the top-right corner. A Settings panel will slide out.

Click "View all Outlook settings" at the bottom of the panel. The full settings dialog opens.

In the left sidebar, click "Mail", then click "Compose and reply".

In the "Email signature" section, type a name for your signature and click "New signature" if you want to create an additional one.

Click "Copy Signature" in DropSig, then click inside the Outlook.com signature editor and paste (Ctrl+V). Your formatted signature will appear.

Pro tip: Outlook.com supports images hosted at public URLs. DropSig images are already hosted and will display correctly.

Check "Automatically include my signature on new messages I compose" and "Automatically include my signature on messages I forward or reply to".

Click "Save". Compose a new email to verify your signature appears at the bottom.

Common issues

Signature disappears after logging out

This is unusual — Outlook.com saves signatures to your Microsoft account. Make sure you clicked Save before closing. If the issue persists, try a different browser.

Formatting is different from DropSig preview

Outlook.com strips some CSS. DropSig templates use compatible table-based HTML that works within these limits. Avoid custom fonts and background colors.

Can't see the signature in sent emails

Check that the auto-include checkboxes are checked. Also verify you're composing from the correct account if you have multiple Microsoft accounts.
