The Division of Information Technology (DoIT) has identified an issue affecting Google Calendar add-ins (such as Webex, Microsoft Teams, and others). A recent update starting on or around May 26th, 2026 from Google has interfered with these integrations, causing some users to experience connectivity errors or authentication prompts when trying to use them.
How to Fix It: The remedy requires clearing the cached data for the affected add-in within your Google account to re-initialize the connection.
We have published a detailed FAQ document with step-by-step instructions on how to quickly resolve this issue: 👉 Page: How to Re-add Cisco Webex Add-In access for Google Calendar
