Microsoft said it is investigating an issue that has left users unable to access Outlook and Teams features and services.
Outlook, the email service popular with both individuals and businesses, has gone down, while Teams, the messaging service that’s widely-used in companies, also appears out for several thousand users.
Thousands of users posted on social media about outages with their email accounts on Saturday evening, complaining about being logged out of their accounts and not being able to log back in.
We're investigating an issue in which users may be unable to access Outlook features and services. Additional details can be found under MO1020913 in the admin center.

According to service status website Downdetector, users began reporting problems with the tech giant's services at around 8.40pm.
Almost 40,000 reports had been received by 9pm, with the issue particularly affecting users in London and Manchester, according to the website.
Microsoft Outlook is one of the most popular email services in the world, with an estimated 400 million users worldwide.
The video-calling service Microsoft Teams, which rose to prominence after the Covid-19 pandemic, has around 320 million worldwide users.

In a follow-up post shortly afterwards, it added: "We're reviewing available telemetry and customer-provided logs to understand the impact.
"We've confirmed this issue is impacting various Microsoft 365 services."
The tech giant also suffered an outage affecting its emails and Teams collaboration app in November, which had similar effects.
The tech giant later posted an update that they “identified a potential cause of impact and have reverted the suspected code to alleviate impact.”
