The web monitoring firm showed that reports dropped to 351 incidents of people raising complaints as of 2:10 ET.
"Users primarily hosted in the North American region attempting to access Outlook.com may be unable to send, receive, or search email. Additional functionality such as Calendar consumed by other services such as Microsoft Teams would also be affected," Microsoft said in an update on its status page.
A "recent change" led to the issue and the company was working to restart portions of the affected infrastructure in order to restore service, Microsoft said in a tweet.
