Deleting a specific email address from autocomplete in Exchange/Office365

[E_G_R2]

Hi,

 

anyone got simple command or script that can be run in powershell to delete an emai address in auto complete?

 

A member of staff accidently used their on email in a all staff/pupil message and as some uses replied their email address now comes up for those users.

 

Cheers

2 options go around each profile and manually delete or run a script and delete the NK2 for everyone but then all auto complete entries will disappear.
