To protect Microsoft 365 services of your company, you need to connect Kaspersky Security for Microsoft Office 365 to your Microsoft 365.
Connecting Kaspersky Security for Microsoft Office 365 to your Microsoft 365 is carried out by granting Kaspersky Security for Microsoft Office 365 a general access to all your Microsoft 365 services (Exchange Online, OneDrive, and SharePoint Online) and Exchange Online Quarantine. When connecting to Microsoft 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 Microsoft 365 and now recommends the use of OAuth 2.0. Decommissioning the basic authentication can help protect your Microsoft 365 from brute force or password spray attacks.
If you have granted Kaspersky Security for Microsoft Office 365 only separate access to your Microsoft 365 services, these services remain protected, but Exchange Online Quarantine items are not displayed in your Microsoft 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 access to all your Microsoft 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 Microsoft 365 organization is registered in Microsoft Azure national clouds (also known as sovereign clouds).
Configuring a connection to Microsoft 365 involves the following:
You can also disconnect the application from your Microsoft 365, if you no longer want to protect the Microsoft 365 services of your company.
