03Paste a designed signature
Copy rendered HTML from the generator or fixer. Paste into the signature editor and confirm images remain before Save. Table-based layouts with hosted https images survive sanitization better than flexbox from AI tools.
Outlook on the web uses the same Settings › Accounts › Signatures path as new Outlook for Windows.
04New Outlook signature image not showing
Community reports and Microsoft Q&A note that pasted images from Word or websites can disappear in the new Outlook editor. Use the editor's picture option with a hosted URL, or paste a signature already built with linked images.
If only recipients cannot see the logo, their client may block external pictures—see the images-not-showing fix guide.
05Signatures in new Outlook vs classic Outlook
Microsoft 365 and Outlook.com mailboxes store signatures in the cloud between new Outlook and Outlook on the web. IMAP and POP accounts, including many Gmail accounts in Outlook, do not roam. Mobile Outlook keeps a separate signature.

FAQ
How do I add a signature in new Outlook?+−
Open Settings > Accounts > Signatures, choose your account, select Add signature and give it a name. Type or paste your signature, choose it as the default for new messages and replies/forwards, then select Save. The same steps work in Outlook on the web.
Why is my image not showing in my new Outlook signature?+−
New Outlook's signature editor often strips images pasted from Word, a website or another email. Insert the logo with the editor's picture option, or paste a signature whose images are hosted on a public https link, and check the preview before saving.
How do I add an email signature in Outlook 365?+−
First check which Outlook you use. In new Outlook or Outlook on the web, go to Settings > Accounts > Signatures. In classic Outlook for Windows, go to File > Options > Mail > Signatures. Both come with Microsoft 365, but the menus are different.
How do I add my signature to replies in new Outlook?+−
In Settings > Accounts > Signatures, set the For replies/forwards default to your signature and select Save. To add it to a single reply, use Message > Insert > Signature while writing.
