If you receive a message stating that emails have not been sent when posting an announcement, please check your course name. If the name has a colon (:) in the title the email tool in Blackboard will not work. This is a known issue with the software and is due to be fixed in an upcoming Service Pack.
Workaround.
- Create the announcement as normal
- Copy the message text
- Post the announcement
- Go to course tools and click send email
- Select the group of users you wish to send the email to e.g. All student users
- Paste the text from the announcement in to the message box
- Click Submit
