To access the application and configure the protection settings for a specific Exchange Online organization, you need to register a workspace for Kaspersky Security for Microsoft Office 365 on the Kaspersky Business Hub portal and complete the initial setup of the application by configuring a Service Account and specifying the protection scope.
Note that once you connect the application to a specific Exchange Online organization, the organization is associated with the workspace used for the current session. You will not be able to connect to it through any other workspace.
