What does the outage mean for visitors and residents in the Canary Islands?
No reports of consequences on Tenerife or the other Canary Islands have emerged so far. No warning from any authority for the islands is known either.
Microsoft 365 is the office cloud behind Outlook, Teams, Word and Excel, and many firms and public bodies use it. Anyone working with a company mailbox or Teams may therefore still have been affected on Thursday.
Emails sent during the outage may arrive late. Microsoft said the queues had become much shorter and were nearing normal levels.
If you are waiting for an important reply, say from a hotel, a landlord or an office, call or write through another channel. Microsoft had named no deadlines, prices or compensation for customers by Friday.
What exactly happened on Thursday?
The outage began on Thursday 12 November 2026 and hit Outlook, Exchange Online, Teams, Microsoft 365 and Copilot. Reports say OneDrive, SharePoint and Power BI were also disrupted.
The outage-tracking platform Downdetector reportedly logged more than 36,000 reports from 72 countries. According to reports, most came at around 18:00 GMT on Thursday.
On the morning of Friday 13 November, recovery was still under way. Reports say mailbox problems and delayed delivery continued.
The figure of more than 20 hours appears in the headline of the Spanish report. No source gives an end time or a total duration, so the figure stays unconfirmed here.
What does Microsoft say about the cause?
Microsoft first cited increased load on part of its infrastructure in several regions. Later it wrote on X of a problem from an earlier expansion of network capacity, which showed up after a recent network change.
Microsoft applied a configuration change to servers that failed automatic health checks. It restarted all affected servers, and says it is working on restoring its front-end servers and optimising traffic.
Charles Lamanna, who is responsible at Microsoft for Copilot (Agents and Platforms), wrote on X: “There is no evidence of malicious or cyber activity.” The Microsoft 365 Status account confirmed this, and the company called it a technical problem with no link to cybersecurity or artificial intelligence.
On the state of recovery, Microsoft said: “We are seeing broad recovery and stability.” Services are coming back step by step.
How often does Microsoft go down, and when were the Canary Islands hit?
On 29 and 30 October 2025, Azure Front Door, a part of the Microsoft cloud, was down for about 8 hours and 20 minutes. A faulty configuration triggered it, and a software bug failed to block that configuration.
Back then, Microsoft 365 was disrupted too. So were Xbox, Minecraft and the check-in systems of Alaska Airlines and Air New Zealand.
On 19 July 2024, an update from the firm CrowdStrike crashed Windows computers, so the fault was not Microsoft’s own. Aena, Spain’s airport operator, reported 16 delayed flights at Tenerife North and gate changes by Binter, a Canary airline; all systems ran again from 11:00.
During the Amazon outage of 20 October 2025, the Canary Islands counted hundreds of incidents. Card terminals at petrol stations, restaurants and shops failed, only cash worked, and Bizum payments (a Spanish mobile payment service) were disrupted too.
What happens next?
Once the countermeasures are complete, Microsoft plans to publish a cause report with the new safeguards. It named no date, and features that depend on Exchange may keep causing problems.
Whether customers will receive compensation or credits is not documented. Current updates appear on the Microsoft 365 status page and on the Microsoft 365 Status account on X.
