   We are actively investigating reports of slow image loading when composing a new email. This is only specific to the Xink add-in in Outlook on the web. Initial analysis confirms the issue does not occur in Outlook Classic or the New Outlook preview. Affected users may experience delayed rendering of signature images, intermittent image load errors, or instances where images fail to load entirely. Evidence points to a performance degradation in the Microsoft API used by the add-in to retrieve signature assets in Outlook on the web.
