Microsoft has said it is “investigating an issue” after users reported problems with Outlook and Teams.
In a post on X, Microsoft 365 Status said: “We’re investigating an issue impacting users attempting to access Exchange Online or functionality within Microsoft Teams calendar.”
Microsoft Exchange Online is a platform for business communication that has a mail server and cloud apps for email, contacts, and calendars.
Down Detector, a website that tracks outages, said problems started at approximately 8am on Monday morning.
It said 87% of reported problems involved Outlook, when the email application is accessed through the web.
Other reported problems, according to Down Detector, included connection to the server and logging in.
Microsoft directed affected users to its admin centre, a page that is intended for those who have access to business networks and other professionals who manage IT networks. The page requires a login.
