It is very easy for hackers to create a fake e-mail address that displays any name they want in attempt to trick end-users. To help identify the authenticity of an e-mail address, we encourage everyone in an organization to set a profile photo.
Profile photos remove the anonymity and add a human touch in e-mail interactions. When all employees have accurate profile photos, it is easy to spot when there is a fake e-mail from a sender pretending to be someone they are not.
