Imagine starting your work day as usual, only to discover that you cannot send an email, communicate with your colleagues via Teams, or access the files you need. Your device is working, your Internet connection is intact, but the services you rely on to get your work done are no longer responding. You may discover that you have many ways to communicate, but you do not know how to reach someone you need outside of the platform you are used to using.
The widespread failure that struck Microsoft services on November 12, 2026, and its repercussions extended to today, raised a question that goes beyond the technical problem itself: Has the abundance of means of communication made us more able to communicate, or more dependent on the systems that provide them?
Services including Outlook and Teams were affected, in addition to other applications linked to the Microsoft 365 system. What has disrupted the businesses of users and organizations that depend on them for correspondence, meetings, and information exchange.
Always connected... but on one platform
Over the past years, communication at work has become easier than ever. You can hold a meeting between employees in different countries within seconds, exchange files instantly, and follow up on conversations and projects from a single device.
But this ease hides a paradox worth noting. We may use multiple applications and think we have different options, but they all rely on a common technical architecture. When this structure breaks down, we may lose more than one means of communication at the same time.
It's no longer just a question of email being down, but of how our business and professional relationships are tied to services we may have no direct control over running or restoring.
Do we know how to reach each other?
We may have been accustomed to communicating with a colleague via Teams for years, but do we have his phone number? Does the work team know how to react if the messaging platform suddenly stops? What if the list of contacts and instructions needed to deal with the malfunction are kept within the stopped system itself?
These are not questions about returning to the past, but about our ability to maintain means of communication independent of the applications we use daily.
Reaching others has often become linked more to their digital accounts than to alternative means of communication. We send a message and assume it will arrive, we arrange a meeting and trust that the link will load, and we store our information within platforms that we expect to be constantly available.
But communication does not start or end with the application. The ability to reach a person, exchange information with him, and act when the usual means cannot be used, remains an essential part of any professional or human relationship.
When comfort turns into dependence
There is no doubt that digital platforms have improved the way we work, helping to bridge distances and save time. But as these services become more integrated, the potential for multiple functions to be affected by a single disruption increases.
As AI enters email, meetings, file management, and task execution, this network of adoption expands. Downtime of a core service may disrupt other tools that depend on it, even if they perform completely different functions.
This does not mean that the solution lies in using a greater number of applications, because the diversity of interfaces does not guarantee the independence of the architecture on which they operate. It also does not mean dispensing with technology, but rather thinking in advance about alternatives, and knowing what can continue when major services stop.
Communication is bigger than technology
Microsoft's failure can be viewed as a transient operational problem, which is addressed by technical teams and after which services return to normal. But it also provides an opportunity to reflect on the way we have come to organize our communication with others.
Technical progress has given us unprecedented speed in reaching people, but it does not guarantee that this ability will remain available in all circumstances. Between having dozens of applications and maintaining a physical means of reaching others, there may be a difference that we only notice when one service stops.
Perhaps the most important question after this holiday is not about when email or virtual meetings will return, but rather about something simpler: If the applications we use daily stop tomorrow, how many people will we still be able to reach them?
European Union leaders will meet in Dublin, today (Friday), for their first ever summit on artificial intelligence, to discuss how the bloc can catch up with the United States and China, and address financing and other problems, according to a Reuters report.
This summit comes amid growing concerns about a technology that could cause a major transformation in the shape of industries and societies, but it has raised concern in the past few months after a series of incidents that occurred due to out-of-control artificial intelligence systems. This week witnessed more turmoil with the resignation of Jensen Huang, CEO of Nvidia; This deprived this sector of one of its most prominent pioneers.
Leaders in Dublin will evaluate ways to overcome other problems, such as red tape and putting in place preventive controls.
European Council President Antonio Costa wrote in an invitation letter addressed to European Union leaders last week: “In light of the rapid pace of development of artificial intelligence. “I believe that there is now a need to hold the first discussion focusing on this file at the leadership level about the opportunities provided by artificial intelligence, as well as about its impact, which is causing a major transformation in our economies and societies.”
Arthur Mensch, CEO of Mistral AI, and Nobel Prize-winning artificial intelligence pioneer Geoffrey Hinton are scheduled to participate to brief European Union leaders on the latest developments.
Europe is intensifying its efforts to be a prominent player in the field of artificial intelligence. An initiative known as the “Chip Act,” implemented three years ago, appears to fall short of its goal of attracting advanced manufacturing and doubling the EU’s share of the global chip market to 20 percent by 2030.
A plan to build seven giant artificial intelligence factories that include under one roof advanced artificial intelligence processors, software, cloud technology, high-speed connectivity, and data centers has not yet been fully launched, due to disagreement among European Union countries over spending on competitiveness in the Union’s budget for the period 2028-2034.
In addition to artificial intelligence, the leaders are also scheduled to discuss the Ukraine file, which was added to the agenda, a day after American envoys Steve Witkoff and Jared Kushner arrived in Dublin to meet with Ukrainian President Volodymyr Zelensky, following talks they held with Russian President Vladimir Putin in Moscow.
A high-ranking European Union official stated that the Union's leaders are likely to discuss their participation in negotiations to end the war, and the potential security guarantees that the Union can provide in the event of a ceasefire.
The disruption of Microsoft services, such as Outlook, Teams, and CoPilot, extended to working hours in the Asia-Pacific region, today, Friday, after affecting thousands of users in the United States, while the technology giant faced difficulties in fixing server problems that it blamed for the outage.
The outage affected government agencies in Australia, Japan and the United States, as well as companies including OpenAI and Anthropic. This is the second outage for Microsoft 365 services this year, raising concerns that recurring outages will lead business customers to question Microsoft's reliability.
Partial improvement in Microsoft services
Microsoft said in its latest statement that it had made modifications to the affected servers, but this step did not succeed in returning the service to normal in a stable manner. It indicated partial improvement in the areas where these amendments were implemented.
The company said on the “X” platform: “We are reviewing additional measures that we can take to improve the stability of the infrastructure in general.”
DownDetector, which tracks outages by compiling status reports from a number of sources, reported more than 18,000 reports of issues with Outlook in the United States at 11:30 p.m. EST (0430 GMT). It also observed outages in a number of Microsoft services in the Asia-Pacific region, including India, Australia, and Japan, early today, Friday, local time.
At the height of the holiday, Down Detector detected more than 130,000 reports of problems with Outlook in the United States at around 1 p.m. EST, Thursday. The malfunction lasted for about 12 hours.
Microsoft said in a notice about the service status that features of Microsoft 365 services that rely on Online Exchange and email were affected, while elements that do not depend on Online Exchange remained functional. Exchange Online is the company's cloud messaging platform, which provides email, calendar, contacts and tasks services.
The company added that it “does not have any information” indicating that the malfunction was the result of malicious electronic activity or a cyber attack.
Australian Home Affairs and Cyber Security Minister Tony Burke said that Microsoft does not believe it is dealing with a cyber attack.
“They believe they are dealing, in some ways, with something similar to what we saw with CrowdStrike, where a software update led to a glitch,” Burke explained in a press conference.
“The impact they are dealing with... is largely focused on email systems,” he added.
The holidays extend to government agencies, airlines, and artificial intelligence
The Australian Intelligence Agency and the Federal Police were among those affected by this outage on Friday.
The 2024 Crowd Strike outage was one of the largest Internet disruptions, crippling technology systems in hospitals, banks and airports, highlighting the fragility of interconnected technologies around the world.
The US House of Representatives indicated that the malfunction affected its users, and that its engineers were working with Microsoft.
Japanese Deputy Chief Cabinet Secretary Masanao Ozaki told reporters that the malfunction affects the infrastructure of government information systems.
The two American artificial intelligence companies, “Open AI” and “Anthropic,” said that they encountered problems with Microsoft’s connectivity services, while the Indian airlines, “IndiGo” and “Acasa Air,” said that their email support services were affected.
Josh Gilbert, a market analyst at the eToro trading platform, pointed out that investors are likely to overcome the impact of the outage, but repeated outages may harm Microsoft in the long term.
Microsoft faced a disruption in its 365 services last January, as well as in October of last year.
Last month, Microsoft reported a malfunction in its cloud platform (Azure), affecting its productivity software package and a group of industries around the world.
