A medium-sized enterprise has deployed a Palo Alto Networks firewall in a branch office. They use App-ID to control access to cloud applications. Recently, they migrated from on-premises Exchange to Office 365. They have a security rule that allows 'office365-base' for all users. However, users report that they cannot access their Office 365 email via Outlook client, although web access works fine. The firewall logs show that the traffic is being allowed as 'office365-base' but no other Office 365 sub-applications are seen. The IT team suspects that App-ID is not fully identifying the Outlook client traffic. What should they do to resolve this issue?

A global company uses a Palo Alto Networks firewall at its headquarters. They have a security policy that allows 'web-browsing' and 'ssl' for all users. Recently, they deployed a new custom web application for internal use that runs on TCP port 8443 with SSL. The application is not identified by App-ID as 'web-browsing' or 'ssl', but as 'unknown-tcp'. The security team wants to ensure that only this specific application is allowed, and all other unknown traffic is blocked. They have created a custom App-ID for the application using application override. However, after applying the override, the traffic is still shown as 'unknown-tcp' in logs. What is the most likely reason?
