There was a recent incident where our users were facing issues with stale authentication for several Microsoft applications including Microsoft Outlook, Microsoft To Do, Microsoft Office 365, Microsoft Exchange, and OneDrive on our platform. We're happy to report that this incident has been resolved.
For affected action steps, you can replay your Zap runs once you have reconnected your account. For Zaps using triggers from these affected apps, Zaps would not have received events to trigger the Zap due to the stale authentication, so Zap runs would not have been processed during this time.
We recommend reviewing your workflows to see if there were missing Zap runs and manually enter missing data as needed.
If you have further issues or require additional assistance, feel free to reach out to our support team at https://zapier.com/app/get-help.
We appreciate your understanding during this incident and apologize for any inconvenience it may have caused.
