Signature images appear as attachments in web mail services

Problem

When received by some web mail applications such as Gmail and Yahoo Mail, inline embedded images in signatures are displayed as attachments to the email, and are not part of a signature.

There are a number of known issues and reasons for embedded images to display as attachments in web-based email clients. If you encounter this issue, check that the signature images display correctly when using the Outlook desktop client, Outlook on the web, or the Outlook app on iOS / Android devices.

Due to the various methods that mail clients use to display or attach images included in emails, we are unable to troubleshoot this problem when it occurs with an external webmail service.

Signature 365 is able to be configured to hotlink images in signatures, however this feature must be requested by the support team. The articles below detail the pros and cons of this method, and how to request this is enabled.
