No, they didn't. Stop listening to this BS from the Clinton campaign.
Colin Powell used a private email account (I think it was AOL), back before there was any policy against doing so. But, that was when use of email at Dept. of State wasn't widespread, and one of the things Powell eventually did was "put a computer on every desk" to make it possible.
Madeline Albright and Condoleeza Rice didn't use email at all, although their staff reportedly did. This was confirmed by the Inspector General.
By the time Clinton took office as SoS, there were explicit policies against it. An announcement went out to Dept. of State staff reiterating that policy, undersigned by Clinton. She later told the FBI she wasn't aware of that message -- one of her many lapses of memory.
In fact, an ambassador to Kenya was about to be disciplined in 2011 for violating that policy, but he resigned instead.
Powell wrote a memo to Clinton about his initiative. But, he recently told a reporter: "Her people have been trying to pin it on me. The truth is she was using [her personal email] for a year before I sent her a memo telling her what I did."
