New Alert Message in Outlook for CM Add-in

Hi team,

We have recently had users experience a new pop-up when opening Outlook, the message doesn't stop them from accessing outlook nor does it disable or prevent them from using the CM add-in. Just curious if anyone else has come across this and what might be the cause. It started occurring roughly 3 weeks ago to some users not all.

We are using CM10.1 - Windows 10 & 11 

Kind regards,
