You have the ability to set up your own custom labels. You can do this by going into Azure Information Protection and clicking on the labels tag, and clicking Add new label. Give the label a name and a description. You can then select a color for the label, and also whether you want to enable automatic protection. When you set up the protection, you can either set permissions, which allows you to configure the file expiration date, and whether or not to allow offline access. Or you can allow the user to set the permissions on the document at the time of creation. You then set the conditions that will activate the protection rule associated with the label.

There are a large number of predefined conditions, but you can also create your own custom condition. The custom condition will be activated when the text pattern you've specified appears in a document. After you have created your label and any associated protection conditions and rules, you must associate it with a policy. Do this by selecting a policy from information protection policies. Go into the policy and add the newly created label. To enable data classification and protection on client machines, you must install the AzInfoProtection software. With this installed, applications like Office 365 will get the information protection toolbar. When a phrase is typed that matches one of the conditions in your rules, the user will be prompted to apply the associated label. Information protection can also be applied through the context menu of Windows Explorer by selecting a file, right-clicking and selecting Classify and protect.
