Service	Reported Impact	Last Update
Outlook (web & mobile)	Over 12,000 users flagging email access issues	Service still degraded
Microsoft 365 (Word, Excel, Teams, onedrive)	~16,000 reports of authentication or sync failures	Partial restoration in select regions
Microsoft store (online & Windows Store app)	Thousands unable too download or update apps	Availability intermittent

Source: TechRepublic reported a peak at 12 p.m. PT with 16,000 total problem reports, of which 12,000 were Outlook‑specific【1】.

Timeline of the Outage

1. 02:00 PT – Initial latency reported on the Microsoft 365 health dashboard.
2. 08:30 PT – Outlook login errors start appearing for corporate tenants.
3. 12:00 PT – Spike in user complaints; the outage reaches a maximum of ~16,000 active tickets.
4. 13:45 PT – Microsoft acknowledges the issue and opens a public incident thread.
5. 15:00 PT – Partial service restoration for OneDrive in North America; Outlook still experiencing “service unavailable” errors.

How the Disruption Affects Different Users

• Enterprise admins: Authentication failures across Azure AD, causing Single Sign‑On (SSO) breakdown for Office apps.
• Remote workers: Missed email notifications, stalled Teams calls, and blocked access to shared files on OneDrive.
• Consumers: Unable to purchase or update apps via the Microsoft Store,affecting Windows 11 users and Xbox console owners.

Immediate Troubleshooting Steps

1. Check the Microsoft Service Health Dashboard – Verify weather the outage status for Outlook, 365, or Store has changed.
2. Refresh authentication tokens – Sign out of all Office apps, clear browser cookies, then sign back in.
3. Use alternate access points –

• for email: Switch to Outlook desktop client or Outlook mobile app (if web is down).
• For files: Access OneDrive via the desktop sync client rather of the web portal.
• Leverage fallback interaction tools – Slack,Google Workspace,or proprietary chat solutions can bridge temporary Teams gaps.
• Monitor official Microsoft channels – Follow the @Microsoft365Twitter account for real‑time updates.

Best‑Practice tips for Business Continuity

• Implement multi‑cloud redundancy: Keep a secondary email routing domain (e.g., Gmail for Business) to forward critical messages when Outlook is down.
• Enable offline file access: Configure onedrive for Business to retain local copies of essential documents.
• Create an outage response playbook: Include checklists for verifying service health, notifying stakeholders, and escalating to Microsoft support.
• Document user impact metrics: Track the number of failed login attempts, ticket volume, and resolution times to report to senior management.

Real‑World Example: Global Marketing agency’s Response

A global marketing agency with 350 employees reported:

• Impact: 78% of the team could not access client email threads, delaying campaign approvals.
• Action taken:

1. Shifted all client communications to a temporary Gmail alias.
2. Utilized Dropbox for file sharing while OneDrive sync stalled.
3. Conducted a “status call” on Zoom (outside Microsoft Teams) to coordinate next steps.
4. Outcome: The agency limited downtime to 4 hours, preventing revenue loss and preserving client confidence.

Expected Resolution Timeline

• Short‑term: microsoft aims to restore full Outlook functionality within the next 2–3 hours, based on the current incident progress.
• Mid‑term: Full Microsoft 365 suite (including Teams and SharePoint) expected to be back to normal operation by end‑day UTC.
• Long‑term: Post‑incident analysis will focus on Azure AD authentication pipelines and Store backend services to mitigate recurrence.
