Hi,
I, too, highly recommend to contact Tech Sup asap. You want to make sure that your data is protected and not
accessable from anywhere. Even tho the users who left might not be able to access your data in any way, however,
I am always rather very cautious.
As mentioned earlier, it might be better if you as the admin protect data, secure data, rather than your users.
Are your users protecting their own data because all data from all users are written to the same location?
Are you running in a Metadata Server environment?
Thanks
Anja
