The problems also hit Microsoft Azure, its its cloud computing platform, which means the effects of the technical problems could be felt on other websites and servers that do not appear to be connected to Microsoft.
The company’s status pages appeared to indicate that the company did not see a problem, at the time of publication. But the Microsoft 365 Twitter account confirmed that it was aware of problems.
It said that it had “identified a potential networking issue and are reviewing telemetry to determine the next troubleshooting steps”.
The problems come less than a day after Microsoft announced its results for the latest quarter. They showed that despite revenue being up slightly, its net income dropped by 12 per cent – and much of the revenue came from the company’s cloud services.
