Microsoft Outlook Down in California: Exchange Online Outage Hits During Work Hours
Microsoft Outlook is down for thousands of users right now, hitting California businesses and remote workers right in the middle of the workday. Early reports point to a broader Microsoft Exchange Online outage that's knocking out email and causing authentication failures, meaning some people can't even log in.

Downdetector is showing a sharp spike in outage reports, and searches for "outlook down" are surging. If you're staring at a loading screen or getting bounced back to a login prompt that won't accept your credentials, you're not alone.
This is a developing story. Details are still coming in and the scope of the outage may change.
What's Breaking Down
According to early reports, the problems include straight-up email failures and authentication issues tied to Microsoft Exchange Online, the backend that powers Outlook for millions of business accounts. That combo is rough: users can't send or receive email, and some can't get into the app at all.

Who's Getting Hit
The outage appears widespread, not limited to one region. For California's remote workforce and office-based teams that run on Outlook day-to-day, that means meetings go unconfirmed, client emails go unanswered, and workflows stall. The timing, during core business hours on the West Coast, makes it worse.
What To Do Right Now
Check Microsoft's official service status page for any posted incident updates. Try logging into Outlook on the web as a workaround if the desktop app is the issue. If authentication is the problem, repeated login attempts likely won't help, so sit tight and watch for updates from Microsoft directly. CALWIRE will update this story as more information comes in.
