Following Yahoo’s September announcement of a data breach affecting 500 million user accounts, the company has made it more difficult for Yahoo Mail users to transition to another email service.

At the beginning of October, Yahoo disabled an email forwarding feature, which would allow users to automatically redirect incoming emails sent to their Yahoo address to another account.

The AP first reported this change, citing conversations with several Yahoo customers who sought out the feature in wake of the news regarding the data breach. Yahoo Mail users who had already set up forwarding won’t be affected, but anyone trying to forward their mail now won’t have the option.
