title: Attachment failed when attaching mdf and ldf files to email (MSSQL 2017)
body: <p>I need to attach my database mdf and ldf files to an email.  In MSSQL, I went to properties--->files and found the path, pulled up the files and tried to attach them.  However, the files don't upload and I get a message saying "attachment failed."  I looked up the issue and found that it may be due to permission not being granted, so I changed my permissions and am still having the issue. Are there other reasons that mdf and ldf files may not successfully attach to an email?<br>
  The progress bar does not go up, so I know the files are not being uploaded at all. After about 10 seconds, the error message appears.</p>
