Microsoft Outage: Is Outlook Down or Just You?

If Outlook won’t load or your mails are stuck, it’s probably not your Wi-Fi or your laptop. A global Microsoft outage that started late on Thursday night (12 November) India time knocked out Outlook, Teams features and Copilot for offices worldwide, and it was still not fully fixed when we checked at 5 pm IST on Friday.

Below: a 2-minute way to confirm it, how to keep working, and the scam mails to ignore. One popular “fix” can make things worse, and that’s in section 6.

⚡ Key takeaways

Not just you: Microsoft confirmed the problem hit Exchange Online (Outlook mail), Teams, SharePoint, Microsoft 365 Copilot and Defender XDR, for users “in any region”.
Status (5 pm IST, Fri 13 Nov): Microsoft reported “early signs of stabilization” and recovery in Asia-Pacific first, but had not declared it resolved.
Your mail isn’t lost: Microsoft extended the email retry window to 48 hours, so delayed mails keep trying to deliver instead of bouncing.
Not a hack: Microsoft said it was “not aware of any malicious activity”. Scammers are still using the chaos, so ignore any “reset your Microsoft password” mail or call.
Who should care: office staff on work Outlook, IT teams, students on Teams, and anyone flying who needs to email an airline.

What Happened in the Microsoft Outage, and Where It Stands Now

The trouble began on Thursday afternoon US time, which was late Thursday night in India. Microsoft opened incident MO1550821 and listed Exchange Online, Microsoft Teams, SharePoint Online, Microsoft 365 Copilot and Defender XDR as affected, according to BleepingComputer.

By Friday, outage tracker Downdetector showed Microsoft products hit in 74 countries and territories, RTÉ reported. Business Upturn noted the disruption ran into Friday office hours in India, citing Deccan Herald’s report of Bengaluru tech companies struggling with Outlook, calendars, Teams and Copilot.

Here’s where things stood when we last checked, at about 5 pm IST on Friday, 13 November:

Microsoft reported “incremental improvement” but said service health “remains variable”.
Recovery actions were completed on parts of the infrastructure in Asia-Pacific, with traffic “gradually restored”, and Microsoft said it was extending the same steps to other regions.
Some readers of ABC News in Australia reported Outlook returning, slow and patchy.

If you’re reading this on Saturday, things may be back to normal. Check the live status (section 2) before troubleshooting.

Is Outlook Down or Is It Just You? A 2-Minute Check

Before you restart the router or call IT, run through this quick check.

Open Microsoft’s status page at status.cloud.microsoft and look for Microsoft 365 issues. RTÉ noted the status page wasn’t loading for some users at the peak, which is itself a hint.
If you’re an admin, the Microsoft 365 admin center has Health > Service health with updates for your company.
Ask one colleague on WhatsApp whether their Outlook works. If three people in different homes have the same error, it’s not your Jio or Airtel connection.
Try Outlook on the web (outlook.office.com) in a browser. If both the app and the web fail the same way, the problem is on Microsoft’s side.
Open any other website. If YouTube and Gmail load fine, your internet is fine.

💡 Pro tip

Switching to your phone’s hotspot won’t fix this. The fault is in Microsoft’s servers, not your connection, so a hotspot just burns your mobile data.

If only you are affected and Microsoft’s page shows no issue, it’s a local problem. Then restart Outlook and talk to IT.

What Microsoft Says Caused It (and What It Has Ruled Out)

Microsoft hasn’t published a final root cause for the Microsoft outage yet; that usually comes after an incident closes. Here’s only what the company itself has said.

First, it blamed “elevated infrastructure load across multiple regions”. It then clarified that the load wasn’t caused by more traffic but by “a number of servers being unexpectedly unavailable”, which pushed extra work onto the servers still running, per BleepingComputer and CNBC.

Later updates said a core process on the affected servers, the one that sets up secure connections, became overwhelmed. Microsoft said it was looking at reverting some recent configuration or network changes. On Friday it admitted one fix had failed, saying it had “confirmed that change is not taking as expected” (quoted by RTÉ).

On the hack question, Microsoft was clear: “As of now, we are not aware of any malicious activity that is causing this incident.” A Microsoft spokesperson told ABC News there’s “no indication this is a cyber attack”.

⚠️ Watch out

Viral theories blaming a cyberattack aren’t backed by anything Microsoft has said. Wait for its official report.

What Still Works: Outlook, Teams and Copilot at a Glance

The Microsoft outage didn’t hit every app equally. Teams held up better than Outlook. CNBC reported most Teams access was available, and Business Upturn said calls, meetings, group chats and channel messages mostly worked.

What broke most was anything that depends on Exchange Online, Microsoft’s mail and calendar backend. That’s why a Teams call could work while the meeting invite for it never arrived.

Service	What users saw (as of Fri 13 Nov)	What to do
Outlook mail (app and web)	Mailbox may not open; mails delayed	Use offline copy; call or WhatsApp for urgent things
Outlook calendar and invites	New invites and changes can fail	Share meeting links directly in chat
Teams calls, chats, meetings	Mostly working	Keep using; join by link
SharePoint and OneDrive files	Listed as affected; patchy	Work on a local copy, sync later
Microsoft 365 Copilot	Listed as affected	Don’t depend on it today

One more thing from Microsoft: it extended the email retry window to 48 hours. In plain terms, a mail sent to you during the outage keeps trying to reach you for two days rather than bouncing back. Business Upturn rightly pointed out this isn’t a promise that Outlook will be fixed within 48 hours.

The Fake “Reset Your Password” Mail: Outage Scams to Watch For

Big outages bring scammers. During a Microsoft outage you expect mails about “your account”, so a fake one looks normal. Academics quoted by ABC News warned of phishing risks as email backlogs clear and mails pour in at once.

The Week reported ING in Australia warning that fraudsters may call offering to “fix” the problem, then ask for remote access to your laptop, your email login or an OTP. An Australian IT shop told people to be “very careful” with unsolicited firms offering outage help.

⚠️ Watch out

Scam warning: Microsoft says it “will never cold call you” about a problem with your device, and its real error messages “never include phone numbers”. If a mail, SMS or pop-up during this outage asks you to reset your Microsoft password via a link, call a “Microsoft support” number, install a remote-access app, or share an OTP, it’s a scam. Close it.

How to stay safe this week:

Never click a password reset link you didn’t request. Go to account.microsoft.com yourself, or ask your company IT.
Call back on a known number. If “IT” phones you, hang up and dial your helpdesk’s number from the company intranet or ID card.
Turn on two-step verification for your Microsoft and Gmail accounts if you haven’t. Our two-step verification guide shows it for each app.
Lost money already? Call the national cybercrime helpline 1930 or report at cybercrime.gov.in. Kerala Police notes quick reporting helps officers preserve evidence.

It’s the same playbook as the Diwali greeting scam on WhatsApp: a familiar event, a fake link, a rush to act.

How to Keep Working While Outlook Is Down

Here’s the catch from the top. When Outlook breaks, the instinct is to rebuild the Outlook profile or reinstall Office. During this Microsoft outage, don’t.

Petri’s guidance for admins says to avoid rebuilding Outlook profiles or changing DNS settings until regions are fully back. A rebuilt profile also throws away the offline copy of your mail, the one thing you can still read right now.

Instead, use what’s already on your laptop:

Classic Outlook: go to Send / Receive > Work Offline. Microsoft says this needs Cached Exchange Mode, which keeps a copy of your mail (12 months by default) on your PC.
New Outlook for Windows: offline mode is on by default. Check Settings > General > Offline to confirm. You can read, search and draft mails offline.
Replies can wait in the Outbox. Write them now; they go out when the connection returns.
Move urgent things to phone or WhatsApp. Tell your manager or client in one line that mail is delayed.
Don’t resend the same mail five times. With the 48-hour retry, all five copies may land at once.
Save files locally. If a SharePoint file opens, download a copy before you edit.

💡 Pro tip

Keep a short list of what clients are waiting on. When mail returns in a rush, it stops you missing the one that matters.

Once things settle, install pending Office updates; the Outlook zero-day fix from this month is still worth having.

Flying or Studying This Weekend? What Airlines and Teams Users Should Do

The outage reached Indian airports. Free Press Journal, citing NDTV, reported that SpiceJet cancelled three Delhi departures (to Pune, Leh and Mumbai) and delayed two more on Friday. Delhi Airport asked passengers to check flight status with their airline before leaving home.

Other airlines mostly saw email trouble, not grounded planes:

IndiGo warned it might not receive passenger emails and pointed people to its other support channels, including its AI assistant 6E Skai.
Akasa Air reported email delays and asked customers to use its 24-hour call centre or social media.
Air India said flights were unaffected and it had rerouted email to keep support running. Air India Express also reported no disruption.

If you’re flying this weekend, check status in the airline’s app and use its official numbers from its website, not a “helpline” from a Google ad or a random tweet.

Students on Teams: classes by link should mostly work. If an invite didn’t arrive, ask your teacher to share the link in the class WhatsApp group, and screenshot any assignment mail you send.

Frequently Asked Questions

Is Microsoft Outlook down right now?

It was partly down as of 5 pm IST on Friday, 13 November, with recovery starting in Asia-Pacific. Check status.cloud.microsoft or ask a colleague; if their Outlook works and yours doesn’t, the problem is local.

Will I lose emails because of the Microsoft outage?

Microsoft extended its retry window to 48 hours so delayed mails keep trying to deliver. Expect late, bunched-up mail rather than lost mail, and check with the sender if something important doesn’t show up after recovery.

Was the Microsoft outage a cyberattack?

Microsoft said it was not aware of any malicious activity, and a spokesperson said there was no indication of a cyberattack. The company has not yet published a final root cause.

Does Teams work during the outage?

Mostly. Reports said calls, chats and meetings largely worked, but calendar invites and scheduling could fail because they depend on Outlook’s backend.

The Bottom Line

This one is on Microsoft’s side, so your router, hotspot and Office reinstall won’t fix it. Confirm with the status page, switch to offline Outlook and WhatsApp for urgent work, and treat every “Microsoft support” mail or call this week as fake until proven otherwise.

Next step: take five minutes to set up a passkey on your Microsoft account so a phishing link can’t steal your password in the first place.
