Between July 1st and 3rd, there were many cases where emails sent by faculty and staff from YNU mail were blocked by the system due to malware judgment and did not reach the destination (the destination is mainly faculty and staff).

It is thought that the cause is a false positive by the ATP (security measure solution) of Office 365 introduced by the university,
but if there is a possibility that the e-mail will not be delivered during the relevant period (Example: I contacted an insider about the date of the meeting, but did not receive a reply),
please resend it.
