Catch Phish Upgrade Needed Before Microsoft Exchange Online Token Shutdown

Incident Report for Breach Secure Now

Monitoring

Microsoft will shut off their legacy Exchange Online Token in October. This change affects older Catch Phish deployments.

Partners currently using the workaround (re-enabling Exchange Online Tokens) must upgrade to the latest version of Catch Phish from the Microsoft Add-on Store.

Partners who have not yet acted and are just learning about this deadline also need to upgrade.

Upgrades can be completed by following the instructions in the Help Center. Alternatively, partners can open a support ticket, and our team will assist with the deployment.
