User impact: Users may be unable to access, view, add, or select public folders and calendars in Outlook on the web.

Current status: Our deployment of the fix is ongoing, and some users may begin to see relief as it saturates throughout the affected environment. We expect it may take until our next scheduled update to saturate throughout 95 percent of the affected environment, resolving the issue for most users by that time, at which point we’ll continue to monitor its progress to completion. 

Scope of impact: Some users attempting to perform multiple public folder or calendar related actions in Outlook on the web may be impacted.

Start time: Tuesday, April 11, 2023, at 11:37 AM UTC
