Office 365: Outlook (email and Teams calendar)
Microsoft has posted a service degradation notice about Outlook connectivity to Exchange Online. It appears to be a global issue affecting all, or at least most M365 tenants, not just OHIO. We do have reports from OHIO users that we are impacted. It also affects the calendar functionality in Teams, since that data is pulled from Exchange Online.
Other applications maybe impacted and will be communicated as soon as we are aware of them.
Affected services: Exchange Online Teams Calendar
