Email Problems in Coventry

We are in Coventry with Matrix Lasers this morning, The issue today is that random emails are not being received after checking all machines that have been authorised to collect the email for the company we decide that it seems possible an ex employee may have been receiving email at home so the safest thing to do at this stage is change the password and retest.
