This change contained a regression, preventing users from opening Shared Calendars in the Outlook   desktop app. We\u2019ve reverted the change and have internally validated its efficacy at resolving impact. Most users should experience gradual improvement or mitigation while the change fully saturates throughout the environment.<\/p>\n<p>  If you continue to experience issues with your shared calendars,
