iTnews reported on 13 November that Microsoft is in a major outage that is "potentially" affecting several Microsoft 365 services worldwide, notably Exchange Online access. iTnews said Australian business users are likely waking to email that will not load. Microsoft first acknowledged the issues at 4.54am AEDT. iTnews noted that Microsoft's own status page was slow to load.
Microsoft said on X that part of its infrastructure has heavy load across several regions, which likely adds to the connection errors. On its status page, it said it has spread connection traffic across its worldwide systems, is moving more off the hit servers, and is restarting them. It has paused all deployments. It is checking whether the extra traffic is real demand or a routing shift. iTnews said the status page also lists Teams, SharePoint Online, Copilot 365 and Defender XDR as possibly affected. No cause or restore time is given.
This paragraph is our reading, not Microsoft's claim. Spreading traffic works like opening more checkouts, and restarts clear overloaded servers. The real-demand question matters because a true surge needs more capacity, while a routing shift needs a routing fix. If email, chat and security tools share one entry layer, they could fail together. Keep a way to reach staff outside Microsoft, and run status checks hosted elsewhere.
