You might notice that images in your email signature are displayed as a gray box (shown below) when you're writing an email or replying to a message.
We're working to identify the root cause and will update this article when we have more information. Please note that the images only show as gray boxes when you're writing an email, and appear as expected to the recipients after you send the email.
