This post is based on Microsoft’s public statements as reported by major news outlets on November 12 and 13, 2026. Microsoft had not published its post-incident review when we wrote it, so details about the cause may change. We will update this page when Microsoft shares more.

01 — What happened in the Microsoft outage

What happened in the Microsoft outage

On Thursday, November 12, 2026, users began reporting that they could not open Outlook. Microsoft first said it was investigating problems reaching Exchange Online mailboxes in the Americas, then widened the scope, saying Microsoft 365 connectivity could be affected for users in any region.

TechRadar reported that Microsoft’s status page listed Exchange Online, Teams, SharePoint Online, Copilot and Defender XDR among the impacted services. Users also reported problems with OneDrive, Planner and To Do. Al Jazeera reported Downdetector complaints from 74 countries and territories within about an hour of the first reports.

The disruption reached far beyond office workers. Al Jazeera reported effects on government systems in Singapore and Japan, and ABC News reported that New York City Emergency Management warned of delays to city email and online services that rely on Microsoft. In the UK, a government spokesperson said it was working with Microsoft to assess the impact.

By the afternoon of November 13 (UTC), Microsoft reported “encouraging recovery progress”, with broader improvements in North America and sustained improvements across much of Europe, according to TechRadar. Reports were falling but had not returned to normal.

03 — What Microsoft has said about the cause

What Microsoft has said about the cause

Microsoft’s explanation changed as the incident developed. In a post on X on November 12, it said some infrastructure was under “elevated load” and that it was redistributing traffic, TechCrunch reported. Later, Microsoft clarified that user traffic had not surged; instead, a number of servers had become unexpectedly unavailable, and their work moved onto the machines still running.

Attention then turned to the automated health checks that decide whether a server can take traffic. Microsoft said it was testing a configuration change to fix servers failing those checks. According to ABC News, some servers that returned to service could become unresponsive again once they received traffic, which matches the second wave of reports on the morning of November 13.

On security, Microsoft executive vice president Charles Lamanna said there was no indication the outage was the result of malicious or cyber activity, Al Jazeera reported. Euronews concluded that the incident was a problem of access, not theft, and that nothing Microsoft had said suggested customer data was exposed or lost.

A full root cause will come from Microsoft’s post-incident review. Until then, treat any other explanation you read online as unconfirmed.

04 — Why an email outage hits video studios so hard

Why an email outage hits video studios so hard

Video post-production runs on links and messages more than most businesses realise. When Outlook, Teams or OneDrive stop working, these parts of a studio’s day stop with them:

  • Footage intake: clients and shooters send upload links by email. If the link sits in an inbox you cannot open, the edit cannot start.
  • Briefs and references: music choices, shot lists and style notes are often buried in email threads.
  • Review and approval: feedback on cuts, revision notes and final approvals usually arrive by email or Teams.
  • Delivery: final download links, invoices and payment confirmations go out by email.
  • Shared storage: studios that keep projects or proxies in OneDrive or SharePoint may lose access to working files.

The deadlines do not move. A wedding film promised for Friday or a real estate listing promised for tomorrow morning is still due, even if the cloud is down. That is why the studios that kept working this week were the ones with a second route already set up.

Editing from local files, with the cloud as backup, means an outage pauses messages, not the edit itself.
05 — A cloud outage plan for video studios

A cloud outage plan for video studios

You cannot stop Microsoft, Google or any other provider from going down. You can make sure one outage does not stop your business. Here is a plan any studio can put in place in an afternoon.

01

Keep a second contact channel for every client

Collect a phone or WhatsApp number at booking, not just an email address. When email fails, you can still confirm deadlines.

02

Write down where files live

Keep a simple project sheet with each client’s upload link, delivery folder and deadline. Store it somewhere that is not in the same cloud as your email.

03

Use more than one file-transfer service

If your default is OneDrive, keep Dropbox, Google Drive or WeTransfer ready as a backup route, and the reverse.

04

Edit from local drives

Work from footage on local or network storage, with the cloud as a sync and backup layer, not the only copy.

05

Follow the 3-2-1 rule

Three copies, on two types of media, with one off-site. Our 3-2-1 backup strategy guide walks through it.

06

Prepare an outage message

A short, ready-to-send note telling clients what is affected, that their files are safe and when you will update them.

07

Bookmark status pages

Microsoft’s service health dashboard and your other providers’ status pages tell you whether the problem is yours or theirs.

08

Add buffer to critical deadlines

For event-driven deliveries, deliver a day early when you can.

06 — Moving footage and deliveries when one…

Moving footage and deliveries when one service is down

Most outages hit one provider, not all of them. Having accounts ready on several services means you can switch in minutes.

Whichever route you use, follow the same safety basics: share links only with the people who need them, set expiry dates where you can, and never send passwords in the same message as the link. Our guide to keeping client footage safe when you outsource editing covers this in detail, and how to send wedding footage to an editor explains folder structure.

07 — Watch for scams after the outage

Watch for scams after the outage

Large outages attract scammers. Euronews warned that outages often bring phishing attempts, and the Defender XDR disruption could weaken security monitoring for some organisations while it lasts.

  • Fake “re-login” emails: messages claiming you must sign in again to restore your mailbox. Go to the service directly, never through an email link.
  • Fake delivery or payment notices: scammers copy delayed invoices and file-share alerts to steal logins or payments.
  • “Support” calls and messages: Microsoft does not cold-call customers to fix outages.

Our guide to phishing scams targeting wedding videographers shows the patterns to watch for, and the website security checklist for videographers covers two-factor sign-in and other basics.

08 — What to check once services are back

What to check once services are back

When Outlook and OneDrive return, do a short clean-up before you carry on as normal.

01

Look for delayed emails

TechRadar reported that Microsoft extended its email timeout window to 48 hours to protect delayed messages. Expect late arrivals, and re-check upload links and approvals from the outage window.

02

Confirm every live deadline with clients

Send one short message per active project.

03

Check sync status

Make sure OneDrive or SharePoint folders finished syncing and no files are stuck or duplicated.

04

Re-send anything that bounced

Invoices, delivery links and revision notes.

05

Review what broke

Note which step stopped your work, and fix that one first in your outage plan.

06

Read Microsoft’s post-incident review

When it is published, it will explain the root cause and any changes Microsoft is making.

09 — How Cut Pro Media keeps edits moving

How Cut Pro Media keeps edits moving

Cut Pro Media is a B2B post-production studio that edits for wedding studios, real estate media companies, brands and agencies. Clients send footage through Dropbox, Google Drive or WeTransfer, so a single provider going down does not block an edit, and we can switch routes when one fails.

Each client works with the same dedicated editor, and every project includes up to 2 hours of revisions (music changes not included). Turnaround is 24 hours for real estate, 1–3 working days for commercial, product video and ads, 5–10 days for wedding photos and 10–15 days for wedding films. See full pricing and how our editing workflow runs from upload to delivery.

We edit every kind of video: wedding, real estate, commercial, product, online ads, corporate, interview, testimonial, social media, music, sports, church and holiday videos, plus wedding photo editing.
