When trying to activate the Office365 (O365) securlet, when redirected back to CloudSOC after accepting permissions for app in O365, receive the following error:
Failed to get authorization token from . Please contact the Symantec CloudSOC support team.
Azure returned an empty response when getting access token. Backend log shows "Resource 'https://<domain>-my.sharepoint.com' is disabled" and got a 400 response from Azure. The reason that an empty response was returned was due to Sharepoint not having been configured in Office 365.
Complete the Sharepoint configuration in the Office 365 environment before attempting to activate the securlet.
