A Microsoft outage affecting Microsoft 365 services brought some Vancouver offices to a standstill on Thursday and was broadly restored by early Friday, with Microsoft saying it resulted from a network capacity upgrade.
The Story
Email bouncebacks and recurring errors in corporate Microsoft apps prompted some Vancouver workers to take an early lunch, and the disruption continued after lunch on Thursday.
As the outage went on, one mechanical engineer-in-training said she started texting clients and slowed her day to get through the disruption.
The outage affected multiple Microsoft 365 services, including Outlook, Teams and AI assistant Copilot, and was broadly restored by early Friday.
In a post on X, Microsoft said the disruption was caused by a network capacity upgrade and was not related to cyber or AI agents.
Charles Lamanna, an executive vice-president at Microsoft, said the company is reviewing what happened and how it can prevent similar issues in the future.
