On September 5, 2012, Microsoft updated its publicly trusted SSL infrastructure with a new 2,048-bit root (the Baltimore CyberTrust Root) in order to comply with the latest industry standards for minimal key strength certificates. To benefit from this update, Windows Intune, which currently uses the GTE CyberTrust Global Root, is changing its root to Baltimore CyberTrust. This update will require a maintenance window of approximately 8-hours during which the service will be unavailable to customers.  Additional information, including maintenance window dates and times, will be provided on the Windows Intune Admin Console Notice Board Alert. 

 

Maintenance window is scheduled for:  (UTC) 4/20/2013 4:30:00 PM - 4/21/2013 12:30:00 AM. You can also find this information on our Service Status Page at http://status.manage.microsoft.com

 

As a result of this change, connectivity issues may occur when the Baltimore CyberTrust Root certificate is not installed on client computers that are managed by Windows Intune. You can find more information about this, including symptoms and resolutions, using the following article http://support.microsoft.com/kb/2831435.

 

Baltimore-based certificates are not supported on Android devices of versions earlier than 2.3.4 (Gingerbread); therefore, these devices may be unable to connect to the Windows Intune service after this change. You can find more information about this, including symptoms and resolutions, using the following article http://support.microsoft.com/kb/2832607.
