Installing and using the Outlook add-on

The purpose of the Coro add-in for Microsoft 365 is to allow end users to report to their security personnel on suspicious emails in their inboxes, as well as to report on emails that have been flagged by the Coro protection and moved to the Suspected folder when the user believes that the flagging was unjustified.

The feedback provided by the end users via the add-in is communicated to the Coro administrators via the Coro Actionboard as part of the Email security tickets that require review.

After examining the ticket, the administrator may decide to adopt user feedback by approving or discarding the respective email, or allowlisting/blocklisting the sender of the email in question, or even allowlisting/blocklisting the entire email network domain of the sender.
