Configuring a connection to Office 365

To protect Office 365 services of your company, you need to connect Kaspersky Security for Microsoft Office 365 to your Office 365.

Connecting Kaspersky Security for Microsoft Office 365 to your Office 365 is carried out by granting Kaspersky Security for Microsoft Office 365 a general consent to access all your Office 365 services (Exchange Online, OneDrive, and SharePoint Online) and Exchange Online Quarantine. When connecting to Office 365, Kaspersky Security for Microsoft Office 365 uses OAuth 2.0, an open standard for access delegation. This standard allows users to grant websites or applications access to information on other websites, without disclosing the passwords. In contrast to OAuth 2.0, the old basic authentication protocol requires a user name and a password for access.

As from October 1, 2022, Microsoft Corporation stops supporting the basic authentication as a method for accessing Office 365 and now recommends the use of OAuth 2.0. Decommissioning the basic authentication can help protect your Office 365 from brute force or password spray attacks.

If you have granted Kaspersky Security for Microsoft Office 365 only separate consents to access your Office 365 services, these services remain protected, but Exchange Online Quarantine items are not displayed in your Office 365 Quarantine, while they are available in the Exchange Online web console. At that, you should grant Kaspersky Security for Microsoft Office 365 a general consent to access all your Office 365 services and Exchange Online Quarantine to ensure that Kaspersky Security for Microsoft Office 365 operates on a full scale.

You cannot use Kaspersky Security for Microsoft Office 365 if your Office 365 organization is registered in Microsoft Azure national clouds (also known as sovereign clouds).

Configuring a connection to Office 365 involves the following:

• When you connect the application to an Office 365 organization, the workspace used for the current session is tied to this organization. To protect Office 365 services of another organization, you must register a new company on the Kaspersky Business Hub portal.
• After you disconnect a workspace from an Office 365 organization, you can connect this organization to the same or any other workspace.

You can also disconnect the application from your Office 365, if you no longer want to protect the Office 365 services of your company.
