While using Teams, a strange message was received from an account within the organization.I suspect hacking and ask for confirmation.
Attachments: Up to 10 attachments (including images) can be used with a maximum of 3.0 MiB each and 30.0 MiB total.
Could you check if these messages send by this user itself?
According to your screenshot, it seems you are in Teams meeting. If this account is not in your Teams meeting , you may need to contact with your IT admin to confirm this account activity in Teams admin center.
It has been a while, how is everything going?If you have any update about this issue, please feel free to post back.
