# Microsoft 364 Microsoft 364, sometimes written as Microsoft 363, is a joke nickname that took hold after Microsoft 365 suffered a widespread outage starting November 12th, 2026, knocking out Outlook, Teams and Copilot for roughly a day. Office workers mocked the '365' branding by subtracting a day or two from the year and begging engineers to take their time with the fix. By Friday the 13th, TikTok videos riffing on the gag had collected millions of views across accounts like @caro.sidequest and @alfonsofoster_. ## Origin Microsoft 365, the productivity suite covering Outlook, Teams, SharePoint and Copilot, went down for users in dozens of countries starting the afternoon of November 12th, 2026, with Exchange Online recovery attempts failing and extending the disruption into Friday the 13th[2]. The outage hit hundreds of thousands of accounts across Asia, Europe and the Middle East in particular, where it landed during active business hours[2]. The nickname surfaced the same day on X, where users riffed on the '365' number by subtracting the days lost. On November 12th, @MikeBeauvais posted 'Let's circle back then / no point coming back until January,' a joke about an outage-induced vacation that collected more than 1.7 million views and 147,021 likes within about 21 hours[4]. Economic Times credited those posts, along with edited logos swapping the '5' for a '4,' as the seeds of the 'Microsoft 364' tag[1]. - **Platform:** X / TikTok (viral spread) - **Creator:** Unknown - **Date:** 2026 ## Overview Posts under the Microsoft 364 banner typically fall into a few buckets. One batch alters the Microsoft 365 wordmark itself, with the '5' struck through and replaced by a '4' or '3' to mark the days lost to the outage[1]. Another batch is text based, with workers posting mock out-of-office replies and messages telling colleagues there's no point returning until January[3]. Video creators cast the downtime as an unofficial holiday, staging coffee breaks, naps and refusals to clock back in[2]. The tone across the format sits closer to relief than anger. Instead of demanding faster fixes, posters openly thank Microsoft for the accidental time off and ask engineers to 'take their time' with Exchange Online[2]. The pun also doubles as a jab at the brand promise, since '365' implies year-round uptime and a single lost day is enough to rename the product[1]. ## Frequently Asked Questions ### What is Microsoft 364?
