Microsoft announced that it is making strides toward restoring its widely used workplace software as a worldwide outage extends into its second day, causing interruptions in business communication, police crime reporting, court functions, AI tools, and various other services.
The company attributed the disruption to server complications, which also impacted its Copilot AI assistant. A comprehensive rollout of software fixes is reportedly starting to bring stability to the system, and Microsoft stated that it has no evidence of any malicious activities.
Based in Redmond, Washington, Microsoft mentioned it is exploring various methods to pinpoint the issue and restore its servers, employing “a careful strategy to identify and mend the impacted infrastructure.”
In a recent update, Microsoft indicated that it is observing “wider improvements” across North America and much of Europe.

How Microsoft’s global outage is affecting some Montreal services
Outlook and Teams rank among the most utilized workplace applications, boasting hundreds of millions of users. The outage hindered individuals from executing vital tasks such as sending emails, managing schedules, and conducting virtual meetings.
This disruption impacted government entities from Australia to Japan and the United States, delayed trading operations, impeded some firms from releasing earnings, and led airlines to caution customers about communication delays, according to public reports.
This outage is one of the longest in Microsoft’s history and marks the second service disruption the company has faced this year.
Concerns over reliance on technology and cloud systems
Organizations that operate Microsoft services on their own servers, instead of utilizing the cloud, experienced relatively less impact.
Microsoft clarified that the outage particularly affected features associated with Exchange Online, its cloud-based email and scheduling platform, while other standalone applications continued to function.
This situation raises further concerns about the global dependence on a select few Big Tech firms that provide both essential software and the cloud infrastructure that supports it.
In early trading, Microsoft’s shares fell by 0.4 percent, although they have increased approximately 8 percent this year.
The disruptions and financial ramifications from the outage may lead to numerous insurance claims; however, the overall impact on insurers is anticipated to be limited, according to Mario De Cicco, vice-president of European financial institutions at Morningstar DBRS.
De Cicco projected that global insured losses from this incident could range between $300 million and $500 million, significantly lower than the $400 million to $1.5 billion financial impact caused by the 2024 CrowdStrike outage, which disrupted over eight million Windows-based computers.
Microsoft reported Friday that services are gradually being restored following a global outage lasting over 12 hours, which affected users of products like Outlook email, Teams video conferencing, and the Copilot AI assistant.
Caitlin Egen from Control Risks noted that while large global corporations typically have contingency measures, the sudden failure of key services serves as a “wake-up call.”
“For many businesses this morning, it has likely been chaotic trying to figure out how to communicate with others,” she remarked.
Hospitals and transportation systems contend with the outage
The European exchange operator Euronext, which manages exchanges in Paris, Brussels, Lisbon, Amsterdam, Oslo, Athens, and Milan, instructed listed companies to use the phone for communications.
Aviva, which released earnings on Friday, stated it had implemented backup strategies, including providing alternative phone numbers for earnings calls and utilizing Bluetooth to share recordings due to email outages.
Unity Health Toronto reported that its teams are facing challenges with email communications, although patient care remains unaffected by the outage.
In Montreal, the CHUM hospital indicated that the outage impacted appointment requests and certain internal processes.
Tens of thousands of Microsoft users throughout Canada and the United States faced challenges accessing Outlook’s email services, Copilot’s AI platform, and other critical applications on Thursday during a widespread outage. By Thursday evening, Microsoft reported that it was restoring some of its affected servers to full operation.
Via Rail advised that some customers were not receiving emails regarding their journeys and recommended that passengers utilize its train tracker or subscribe to text notifications.
Several federal, provincial, and municipal government departments across Canada also experienced email issues.
In Australia, where the federal police and intelligence agency were impacted by the outage, Cyber Security Minister Tony Burke stated that Microsoft does not suspect a cyberattack.
“The issues they are encountering … are primarily related to email systems,” the minister explained.
A representative of the U.K. government mentioned that it is collaborating with Microsoft to resolve the outage that has affected organizations such as the National Health Service (NHS) and London’s Metropolitan Police.
The Metropolitan Police’s ability to report certain crimes online was hampered by the email access issues, although their response to calls remained unaffected.
The NHS indicated that its local services are adopting alternative methods, including using IT systems or paper records.
American AI leaders OpenAI and Anthropic also encountered problems with Microsoft connectors, while Indian airlines IndiGo, Akasa Air, and Air India reported impacts on their email support services.
After two significant outages in recent weeks — including the CrowdStrike failure — concerns are growing regarding the world’s dependency on Microsoft. Andrew Chang examines what occurred, who is responsible, and explores just how interconnected our lives are with Microsoft.
This occurrence further intensifies discussions about vital software and the underlying cloud infrastructure.
“The larger concern is that this isn’t the first Microsoft 365 outage this year,” remarked Josh Gilbert, a market analyst at trading platform eToro. “If reliability appears to be an ongoing issue, it gives every IT department a reason to reconsider placing even more of their operations in a single provider’s control.”
Microsoft encountered an outage with its 365 services in January of this year, as well as in October of the previous year. Last month, it also faced an outage of its Azure cloud platform, which impacted its suite of productivity software across various industries globally.
Nonetheless, some analysts have raised questions about whether such incidents could drive customers toward competitors, given the substantial switching costs associated with replacing tools that are deeply integrated into daily operations.
