Troubleshoot problems
Attachments might be unavailable
Your network administrator or Internet provider probably blocked 'mail-attachment.googleusercontent.com', the domain that Google uses to host attachments.
For more help, contact your internet service provider.
Blocked for security reasons
To prevent viruses, Gmail doesn't let you attach executable files, such as files ending in .exe.
