What’s happening?
Users are experiencing token expiration errors in Power Automate, which disrupts their workflows and requires reauthentication. The error message indicates that the refresh token has expired due to inactivity.
Reason:
The refresh token is only valid for 90 days of inactivity. If a connection is not used within this period, the refresh token will expire, leading to access token errors when attempting to run flows. Additionally, issues may arise from conditional access policies or changes in user credentials.
Resolution:
- Ensure that the connection is actively used within the 90-day period to prevent token expiration.
- If the error occurs, refresh or reauthenticate the connection to obtain a new access token.
- Check for any conditional access policies that may be affecting the service account or user accounts.
- If the issue persists, enable advanced diagnostics for the service request to allow for deeper investigation.
- Confirm if the affected devices are associated with Azure and check their Device Object IDs.
- If users have recently changed their passwords, ensure that they reauthenticate to update their credentials in the system.
- For further troubleshooting, capture network traces and logs as per the guidelines provided in the support documentation.
