We are aware of an issue affecting the Hoxhunt add-in on Outlook for Android version 5.2623.0. Users on this version will be unable to use the add-in, as it fails to load due to a Microsoft Office.js initialisation error. This appears to affect all Office add-ins on this version, not just Hoxhunt. Impact: Users running Outlook for Android version 5.2623.0 cannot report phishing simulations or emails via the Hoxhunt add-in. Root cause: This is caused by a regression in Microsoft's Outlook for Android release 5.2623.0. The issue has been reported to Microsoft and is being tracked on the Office.js GitHub issue tracker. Workaround: If possible, downgrade to Outlook for Android version 5.2617.1 or earlier, where the add-in works as expected. We are monitoring the situation and will update this page when Microsoft releases a fix.
