Issue
When trying to open an attachment with Thunderbird, below error message appears on your screen:
[Thunderbird] error message:
"Unable to save the attachment. Please check the filename and try again."
This is due to a forwarded message that itself contain an attachment which however generates a bug under thunderbird. This is actually being worked by Thunderbird team which will be corrected for the future version.
Solution
- Below is a temporary proposed solution
- Click on View and then View attachments in messages .
Alternative solution
- If the first does not work, or if there are more than two messages, you can save the file on your hard disk.
- Then right click on the file and click on Save as >OK
- Then open the file from your desktop.
- Open the attachment by double clicking on it.
