If you're a Microsoft 365 Business user, your Outlook's Advance Threat Protection (ATP) service may mistakenly identify an email from Cloud Assess as malicious and move it to a quarantine folder. This can happen when there is a “false-positive” result from Microsoft’s anti-spam/phishing algorithm, which can be triggered by a recipient who had mistakenly marked an email from Cloud Assess as spam.
While we are working hard with third-party consultants and Microsoft to resolve the issue, here are two things you or your administrator can do to immediately allow emails from Cloud Assess and prevent them from being automatically blocked by the ATP service in your Outlook.
You can release the emails held in quarantine
You can create a Spam Filter for your organisation and add assessapp.com to the Allow list
How to release Cloud Assess emails held in quarantine
Please note that you will need administrative privileges on your Microsoft 365 Business account to be able to do this.
Step 1: Go to https://protection.office.com/quarantine and sign in using the Microsoft 365 account with administrative privileges (or go to Review > Quarantine from your Microsoft 365 Defender Homepage).
Step 2: Select the quarantined email. From the top header, click on Release email.
After releasing the message, click on the checkbox to Submit the message to Microsoft to improve detection (false positive).
