Many times you may receive emails in Outlook that are pretending to be someone they are not, even sometimes they may appear to be coming from yourself.
Simple and effective way to see who the sender of each email really is,
- Click on the window where you view incoming emails, then click "view", "add columns"
- Now click "New Column" and name it something like "Sender"
- Change the Type to "Formula", click "edit" and enter the following:
right(([SearchFromEmail],[SearchFromEmail]),InStr(1,[SearchFromEmail],"@")) or right([SearchFromEmail],len([SearchFromEmail])-InStr(1,[SearchFromEmail],"@")) to show just the domain.
