The personal email addresses of nearly 100 people have been exposed by Yarra Trams in yet another data breach involving Victorian commuters.

In an email from a Yarra Trams officer to 91 commuters rejecting their compensation requests on Friday, the private email addresses of each of the commuters was exposed.

The email was sent about 3pm and was followed up by another message 15 minutes later, in which the company attempted to recall the email but instead sent another note exposing the list of private addresses.

One commuter, who requested to be known only as John, said he was furious that his private details had been exposed against his will.

"I'm very disappointed that Yarra Trams was releasing my personal information," John said.
