Outlook email notification when file is updated/content is added

Hi guys,

Super ambitious...

Is anyone aware if it is possible for an email notification (outlook) to be sent to people when a change is made to a document? Using an excel file to add tasks and have someone deal with the tasks, I am trying to make it like an I.T helpdesk with a ticket function.

Essentially, if a requestor adds a row with a request an email notification should be sent
If the helpdesk person adds something to a cell (an update) an email notification should be sent

Is this possible on Excel???

Thanks guys.
