Usando o novo Outlook no Windows para gerenciar e-mails pessoais, calendário e contatos
Hello,
If your email signature image goes missing or breaks over time, it's usually because of how your email client refers to or stores the image, especially if you copied and pasted it or linked to it from an unreliable source. The link to the image might not work anymore or be available to everyone who gets it.
You can try this: Upload your email signature image to a stable, public hosting service and use its direct URL instead of a local file. This should make the image show up every time. After you upload, copy the permanent link and open it in an incognito browser to make sure it loads without needing a login. Then, open your email signature editor and choose the option to add an image via URL. Paste the direct link so that anybody who gets your emails can see the image the same way every time.
I hope this helps. Leave a comment if you have any questions.
Thanks,
