Outage Details
Microsoft is rolling out deprecation of legacy Exchange tokens that may prevent your users from being able to report emails using the Expel custom Office 365 Phishing button.
Expel is working on development and testing of an updated Expel O365/M365 Phishing button for web and desktop applications that will work with the NAA authentication scheme.
Until Expel is able to deploy the newly developed Phishing button, you should follow the instructions from Microsoft (https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/turn-exchange-tokens-on-off) to enable legacy tokens for your tenant. It can take up to 24 hours for this change to take effect.
Contact support if you need assistance with this process.
