Major outage at Microsoft. Systems crashed in 74 countries, Outlook and Teams have not opened for hours

The global access problem, which hit Microsoft's core services such as Outlook, Teams and artificial intelligence assistant Copilot, spread to working hours in the Asia Pacific region after affecting thousands of users in the USA.

The disruption, which lasted for approximately 12 hours, paralyzed the communication networks of public institutions and giant technology companies around the world.

Microsoft announced that despite the technical interventions made on the servers, a permanent solution has not been provided yet and only a partial recovery has been observed.

In the statement made by the company on the X platform, the following statement was used: "We are evaluating what additional measures we can take to improve the overall infrastructure stability."

The company stated that the outage affected Microsoft 365 features connected to Exchange Online and e-mail infrastructure, and announced that services that do not rely on this system continue to work.

It was also noted that there was no information that there was any malicious cyber activity behind the problem.

The second major outage in Microsoft 365 services this year has increased concerns about the reliability of the technology giant among corporate customers.

The company experienced similar 365 outages in January this year and October last year, and last month, disruptions occurred in various sectors worldwide due to the malfunction in the Azure cloud platform.

Josh Gilbert, market analyst at investment platform eToro, said investors can ignore this situation at this stage, but recurring problems could hurt Microsoft in the long run.

"The bigger concern is that this isn't the first 365 outage this year. If reliability starts to look like a recurring issue, that gives every IT department reason to think twice before entrusting more of their business to a single vendor. The market will want to see Microsoft prove it can keep systems up before asking customers to spend more on Copilot," Gilbert said.
