Longtime Hillary Clinton aide Huma Abedin acknowledged both she and the former secretary of state were 'frustrated' when communications fell through because of Clinton's unusual use of a private email system that on occasion made it difficult to 'do her job.'

As part of a public information lawsuit by conservative group Judicial Watch, Abedin was questioned repeatedly about a 2010 email where Clinton wrote she didn't 'want any risk of the personal being accessible.'

That email had been prompted by difficulties Clinton had connecting with a foreign foreign minister, according to the deposition.

Clinton missed the call 'because she never got – I never got her e-mail suggest[ing] – giving us the sign-off to do it. So she wasn't able to do her job, do what she needed to do,' Abedin explained.

Important communications between Clinton and staff had been going to her spam filter because of her private email address.

'We should talk about putting you on State e-mail or releasing your e-mail address to the department so you are not going to spam,' Abedin wrote Clinton at one point.

The issue was a source of frustration on the part of both Abedin and her longtime mentor, who has employed Abedin since her time working for Clinton in the first lady's office.

Asked what she meant about releasing Clinton's closely-guarded personal email address – guarded by staff but denied to some senior government officials – Abedin responded, 'I'm not sure I would know how to define that then or define that now. I might have also just be my -- my being frustrated back at the fact that I wasn't getting her messages. – just reading the exchange, she seems frustrated because she's not able to do her job.'

Abedin in her testimony couldn't recall if she resolved the problem by calling someone or if, 'I on my own said, Here are some solutions so that your e-mails get through to us so that we can place call -- calls to foreign officials.'

Abedin testified in a lawsuit that began by probing her work as a special government employee at the State Department as well as in the private sector

Frustrated: Abedin said Clinton's private email sometimes led important communications to go to spam

Abedin dodged when an attorney conducting the deposition pressed about her about what she meant when she wrote about 'releasing [Clinton's] e-mail address to the department'

'I couldn't tell you,' Abedin responded.

Despite the SNAFU, Clinton didn't' appear to take any affirmative steps to change the situation.

'I don't recall any response, other than once the system was back up and running, that it was -- we just proceeded with business the way it was before,' Abedin said.

'I would imagine anybody who has personal email doesn't want that personal email to be read by anybody else,' Abedin explained. 'I read it the same way as she has written it,' Abedin said, when asked about Clinton's apparent reluctance to engage with the normal system.

Two witnesses to the testimony told Bloomberg described Abedin as being cooperative during the deposition.

Judicial Watch released a new batch of emails between Clinton and Abedin Monday.

In one of them, Clinton shows some knowledge of the need to preserve federal records.

'I have just realized I have no idea how my papers are treated at State,' Clinton wrote in 2009. 'Who manages both my personal and official files?'
