Steps to Replicate

  1. Log in to Blackboard Learn as an administrator

  4. Enroll both users in the Ultra course created in step 2

  5. Navigate to Course Settings

  6. Under Course Tools, open Messages and disable 'Allow course messages' so that messages are sent by email only

  7. Log in as the student and open the course

  8. From the Roster, select the instructor's Email icon

  9. Compose an email and attach a file whose filename contains parentheses, for example: Sample(rename).docx

  10. Send the email

  11. Open the email received by the instructor and select the attachment download link

Observed Behavior:
The attachment download link generated in the email is invalid, preventing the recipient from downloading the attached file.

Expected Behavior:
