When attempting to send email reports to recipients marked in TO, CC, and BCC, the recipients copied in CC and BCC will receive the same email reports repetitively.
For example, if there are 5 recipients in the TO section and 1 recipient in CC, the CC'd recipient will receive 5 email reports.
Resolution
This is working as expected when there are multiple Users enabled in the Users/groups section in the Tasks menu.
If there are 4 recipients (4 users in the Tasks configuration) and not 4 email addresses in the "TO" configuration on the email tab, 4 different reports will be generated. Each report will be sent to its own recipient and to the CC'd address. So, a total of 4 separate emails, each one with one address in TO and one in CC, will be sent.
