Able to Show sender with Notification Rule
I have created a rule within our 365 Enterprise environment to reject any mails larger than 10MB in total, when this happens it notifies the sender that the mail they sent is larger than 10MB and has been blocked. For someone trying to send mails to our staff from an external address it notifies our staff that a mail sent to them exceeds the 10MB and has been rejected.
However, I am trying to have this notification mail show the senders address so the staff can contact them and let them know that they did not receive the mail due to size restrictions.
I have tried different variables in the highlighted section of the below image for example: $$Sender$$ %%Sender%% %SenderAddress% but none of these work. Basically I want it to read "Mail sent to you by Sender Address exceeds the limit of 10MB
