Urgent: Outlook Web inaccessible in Kazakhstan since November 13, 2026

Ask the university’s Microsoft 365 administrator to check Health → Service health → Exchange Online first, because only the tenant-specific dashboard can confirm whether this mailbox is affected by an active incident and provide Microsoft’s restoration updates.

There were broader Outlook/Microsoft 365 outage reports around November 12–13, 2026, but no official information available here confirms a Kazakhstan-wide disruption or provides a reliable restoration time specifically for Kazakhstan. The errors alone do not distinguish a Microsoft incident from a tenant, browser, or network-path problem.

Actions you can take now

1. Open Outlook in an InPrivate/Incognito window using a current version of Edge, Chrome, Firefox, or another supported browser.
   • If it works there, clear cookies and cached data for the Outlook/Office sign-in sites—or clear browsing data for All time.
   • Fully sign out of Microsoft accounts, close every browser window, restart the browser, and sign in again. This is the supported next action when a private-window test succeeds.^1^
   • Ad blockers and pop-up blockers can interfere with Outlook on the web, so temporarily disable them for the Outlook site during the test.^2^
2. Test one genuinely different connection, such as a mobile hotspot instead of the university network.
   • If Outlook works on the hotspot but not the university connection, give that result to university IT; it points to the institutional or ISP network path rather than the mailbox itself.
   • If it fails across different devices, browsers, and networks, report those results because they make local browser remediation less likely.
3. Use another configured Outlook client temporarily, such as Outlook mobile or desktop. This can provide access when the web interface alone is failing, but success does not establish whether the underlying incident has ended.

Actions for the university Microsoft 365 administrator

1. Confirm incident status and restoration estimate

In the Microsoft 365 admin center:

1. Go to Health → Service health.
2. Review Active issues Microsoft is working on for Exchange Online and Office on the web.
3. Open any matching incident and record its:
   • Incident ID
   • User impact
   • Estimated start time
   • Current status
   • Latest update
4. Check Issue history if the incident has already been marked resolved.

Service Support and Helpdesk administrators can view service health. Microsoft posts investigation, mitigation, recovery, and restoration updates on the incident detail page; any trustworthy restoration estimate must come from that entry.^3^

If no matching issue appears, select Report an issue on the Service health page. This allows Microsoft to correlate reports from other organizations.

2. Determine whether incoming mail is being retained

Loss of Outlook Web access does not by itself prove that incoming mail has stopped. Exchange Online provides mailbox storage and mail flow separately from the Outlook Web interface, but delivery during this event must be verified rather than assumed.

The administrator should run a message trace:

1. Open the Exchange admin center.
2. Go to Mail flow → Message trace.
3. Set the affected institutional address as the recipient.
4. Select a date range beginning shortly before the failure.
5. Run the search and inspect the status:
   • Delivered: Exchange Online accepted and delivered the message to the mailbox.
   • Deferred, Rejected, or another status: open the message details to identify what happened.

Message trace can determine whether a particular message was received, rejected, deferred, or delivered by Exchange Online.^4^

For urgent journal correspondence, ask a known sender to send a test message with a unique subject, then have the administrator trace that exact message. Do not ask journals to resend submissions repeatedly until delivery status is known.

3. Escalate if no incident is listed

If the problem persists across browsers and networks and Service health shows no applicable incident, the administrator should open a Microsoft support request:

1. Microsoft 365 admin center → Help & support.
2. Describe the failure as an Exchange Online / Outlook on the web access issue.
3. Include:
   • Start time: November 13, 2026, shortly after 00:00 UTC+5
   • Whether multiple university users are affected
   • Devices, browsers, and networks tested
   • Exact errors and screenshots
   • Service-health findings
   • Message-trace results
4. Select Contact Support and choose phone or email.

Microsoft 365 business support requests require an administrator; if the university purchased all subscriptions through a partner, the administrator must contact that partner instead.^5^
