Frequent logouts from Microsoft services like Outlook, Teams, OneDrive, and Office can be caused by several factors related to settings in the Microsoft 365 Admin Center. Here are some possible causes and recommended steps to resolve the issue:
- Idle Session Timeout: If the idle session timeout is configured, users may be logged out after a period of inactivity. This setting can be adjusted in the Admin Center under Org Settings > Security & Privacy > Idle session timeout. Ensure that the timeout duration is set appropriately for your organization's needs.
- Account Lockout Policies: If users' accounts are being locked out due to incorrect password attempts or other security settings, this can lead to frequent logouts. Review the account lockout threshold settings and ensure they are configured to allow for a reasonable number of failed attempts before locking the account.
- Authentication Issues: Problems with Kerberos authentication or other federation issues can also cause users to be repeatedly prompted for credentials or logged out. Ensure that the authentication methods configured in your AD FS (Active Directory Federation Services) are functioning correctly.
- Browser Settings: Sometimes, browser settings or extensions can interfere with session persistence. Ensure that users are not using settings that clear cookies or cache frequently, as this can lead to session loss.
To troubleshoot, consider the following steps:
- Check and adjust the idle session timeout settings in the Admin Center.
- Review account lockout policies and ensure they are set to a reasonable threshold.
- Verify that authentication methods are functioning correctly and that there are no issues with AD FS.
- Encourage users to check their browser settings and ensure they are not inadvertently clearing session data.
By addressing these areas, you should be able to reduce the frequency of logouts and improve user experience.
