A very important thing that lots of businesses fail to address properly is what to do with a former employees email and login credentials now that they are no longer being used?
Emails will continue to be sent to this account from clients and prospects and any other correspondence but what about login credentials to important websites?
What happens when that employee was the only one with admin privlege to a certain account and now you are locked out?
The solution is not to delete an email unless you have done transfered and removed all association and responsibiliteis that account had with different online platforms.
