Here, it is pointed out that “3rd-party email security scanning software is activating the link.”
Similarly, in a specific Outlook environment, clicking the link resulted in the above symptoms. It is believed that Outlook’s Safe Links may be the cause; however, in this case, it was found that there are no logs of “Account Unblocked” recorded in “Monitoring-Logs.”
Currently, it is not possible to understand the user’s situation from the logs, so I would like you to ensure that logs are recorded even in these cases.
