Microsoft now requires third-party applications, that want to import emails from a Microsoft 365 (Office 365) IMAP service, to use an access token for authenticated connection requests. Basic Authentication, which uses a Username and Password, is no longer supported by Microsoft. The Incisive application will automatically recognise whether the Microsoft account is configured to only allow ‘Managed Authentication’ connections.
You need to register the Incisive application in your Azure Active Directory tenancy, that hosts your Exchange Online and grant it permissions. The AppID and Secret Value, of the app you register, are required for SPM/PHM to access the Microsoft 365 account.
The steps required are:
Register the ‘Message Centre’ as an App
Assign Users & Groups to the App
Assign Permissions to the App
Create a Secret
Enter the App ID and Secret into the Incisive program
