Rebekah Brooks has returned to work as chief executive of the company which publishes The Sun and The Times newspapers.
In an e-mail to staff at News UK, she said it was a "privilege to be back."
"I’ve worked for this company since 1989 doing a variety of jobs from making the tea to becoming CEO 20 years later," she added.
"It’s hard to describe how good it feels to be home. And the Sun is shining!"
Mrs Brooks stepped down as head of News UK in July 2011 in the wake of the phone hacking scandal which saw the closure of News of the World.
She stood trial over charges related to hacking, corrupt payments and perverting the course of justice, but was found not guilty. Soon after she was given a consultancy role in New York in a Murdoch-owned business.
Mrs Brook's return was announced last week in a shake-up that saw Daily Mail deputy editor Tony Gallagher appointed to edit the Sun, who's editor David Dinsmore became chief operation officer at News UK.
In her email, Brooks also expressed sympathy for Sun staff who are still facing trial over alleged corrupt payments for stories.
“It would be wrong to dwell on the past," wrote Brooks, "but it would be wrong not to mention it. Many colleagues and their families have suffered a great deal in recent years and my thoughts are with those who still face unimaginable stress and uncertainty.”
The Guardian reports her email has not been well received by workers at the office. “It made me sick, it’s as if she thinks nothing had happened,” said one.
