Data Rights Management or Information Rights Management is a feature that is accessible only on the Enterprise
Files and e-mails are known as the fragile security points in any organization's security system. When documents not including any indoor protection are sent as e-mail attachments or shared on memory sticks, they are easily available to any one and e-mails without protection can be forwarded outside the organization and damage reputation. That is why you require Information Rights Management, or IRM.
If you allow IRM in Office 365, you can always restrict any type of activities of users, which will permit and restrict the activities of incoming and outgoing of e-mails as files that have been downloaded from SharePoint libraries. The IRM settings can for example permit users to read files but not print or copy them.
Information Rights Management (IRM) assist to organize, manage and protect digital documents by controlling the access of users and will take on documents that have been downloaded from SharePoint Online or OneDrive for Business document libraries and lists.
IRM encode or protect the downloaded files and limits the set of users as well as programs that are given permission to decode these files, as well as limits the rights of the users who are permitted to read files, consequently that they will not able to take actions such as print copies of the files or copy text from them.
