There are a few steps to consider when trying to access attachments in emails:

1. Check your software and internet settings to make sure you have enabled downloading of attachments.
2. Check the size of the attachment; try downloading smaller attachments first then larger attachments.
3. Check if the attachment contains any special characters, or if the attachment was sent to you using an email account that was recently created.
4. Try a different web browser or computer, and check if the attachment is visible there.
5. Open a web-based email service and try downloading the email attachment there.
6. Contact the provider of the email server to see if they can enable the attachment.
