What happened
Microsoft Outlook went down for thousands of users in the UK on the evening of November 12, with some Teams and Copilot users also reporting problems [2]. Microsoft and Alphabet shares both closed higher that day, a coincidence in time with the outage and not a demonstrated link.
Metro.co.uk reported that Outlook was down for thousands of people in the UK. The issue began just after 5.20pm and rose to more than 3,300 reports within 20 minutes, according to the outage tracker Downdetector [2].
Hundreds of other UK users were struggling with Microsoft Teams and Copilot, the company's AI chatbot [2]. Metro also reported that some 60,000 people in the US were experiencing issues with Outlook, with problems first appearing earlier, at 4pm [2].
Users loading Outlook were met with a 'Failed to fetch' error, which Metro describes as a browser sending a request to a server and not hearing back [2]. Two other outlets, GV Wire and The National Scot, carried headlines saying Outlook was down for thousands of users [1][3].
What ATLAS data show
ATLAS's model estimates a fair value of $522.27 for Microsoft, within a range of $357.75 to $610.79. The November 12 close is 1.24% above that estimate. For Alphabet, the model estimate is $285.19, within a range of $226.51 to $359.07, and the close is 5.78% above it. These are model estimates, not promises or advice.

Two share prices moving in the same period as an outage is a coincidence in time, not evidence that one caused the other. The figures come from market closes on November 11 and 12 and may change.
