Is it safe to store data such as account log-in information (for vendor websites, not administrative accounts), settings policies, activation documentation, and operating system keys in a public folder on microsoft exchange and setting the permissions for only members of a specific security group are allowed to add/edit/view the posts?
I find the following two benefits: The exchange server is incrementally backed up every hour and sent off site at night, so in a disaster once the restore is complete the documentation is still available.
Users can update, post, and read as needed on the flow from OWA or outlook.
But I am not aware of security risks I may be presenting.
