I'm unable to access Outlook through the web, desktop client, or mobile app this morning. I'm located in the Midwest. Is anyone else seeing similar problems, or is this limited to certain tenants or regions?

No problems here in Indiana or the Dallas area. Based on the mixed reports, this doesn’t appear to affect every Outlook user and may be tied to particular tenants or backend services.
Mail delivery is working here, but we can’t access the Exchange Admin Center. Changes made through Microsoft Graph PowerShell also aren’t syncing between Entra ID and Exchange. Our organization is in the Eastern US, although much of the tenant is hosted in Central US.
Everything is working normally for me in the Midwest, so it may not be a broad regional outage. It could be isolated to a specific tenant or service cluster.

That sounds similar to what we’re seeing. The public status page doesn’t show anything, but the service still appears to be having issues.
