THE NHS email server has crashed after a test email was accidentally sent to all 1.2 million employees.

A "senior ICT delivery facilitator" sent the test email this morning, with the huge email trail grinding the server to a halt.

Doctors, nurses and other members of NHS staff have now taken to social media to share their email pain.

Many NHS employees have taken to pointing the finger at Roslyn Learmond, who works at NHS South East CSU, for sending the initial email.

One person wrote: "Congratulations to Roslyn Learmond @ NHS South East CSU who has managed to expose a long list of idiots this morning. #nhsemail #replytoall"

NHS digital spokesperson told The Sun Online: "Some users have experienced short delays in the NHS mail system this morning.

"Action has been taken to resolve this issue.

"A number of email accounts have been operating slower than normal due to a NHS mail user setting up an email distribution list which inadvertently included everyone on the NHS mail system.

"As soon as we became aware of the issue we deleted the distribution list so that no one else could respond to it.

"We anticipate the issue will be rectified very soon."

Community programmes manager Olly Benson, who works for NHS England, tweeted: "So the whole NHS has been added to an email list by mistake.

"Currently 54 replies from people asking to be removed. Today will hurt."

He later said he was now up to 68 responses, saying all the emails were from people asking to be unsubscribed.
