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.

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.
