.bad file extension
- 1. A generic file extension used to indicate a bad or corrupt file. Often (but not always) this is a file of a different type which has had the file extension renamed to .bad or had a .bad file extension appended.
- 2. A non-delivered email. A .bad file is an email file that the Windows
SMTP server has been unable to deliver.
Whilst each virtual SMTP server generates .bad message in its own separate Badmail folder, these .bad files are typically located in:
C:\Program Files\Exchsrvr\Mailroot\vsi 1\BadMail
- On systems running Microsoft Exchange server.
- On Windows systems not running Exchange server.
The .bad file is a renamed .eml file, and its content may be viewed by renaming to to .eml and then opening it using a suitable email client.
