Is Outlook down was the question for thousands of users in the United States on Monday, after Microsoft Outlook stopped working for many people around 12:15 p.m. EDT. Users reported trouble sending and receiving emails, and some could not log in at all.
Microsoft Outlook at 12:15 p.m. EDT
Reports of issues began coming in around 12:15 p.m. EDT on Monday, and the problem soon broadened beyond one type of failure. One user said, "Emails are not being received. Showing in my sent folder but not actually sending."
That pattern points to a service problem affecting both directions of mail flow. For a user, that means a message can look sent without reaching the recipient, while incoming mail may never appear in the inbox.
Downdetector and MS status
Downdetector was cited for the timing of the reports, while one user said the MS status page still claimed everything was operational. The same user wrote, "Clearly not operational."
Another user described the outage as a login failure after a normal start to the day, writing, "One hour halter and the problem has not changed, all while MS status page still claims all is operational."
A separate report said Outlook mail kept loading but never showed the inbox. Another said shared folders were disappearing and access was gone, which turned a mail outage into a workspace problem for people who rely on shared folders.
Microsoft Outlook users in the United States
Microsoft Outlook was down for thousands of users in the United States, and the reports included people who could not send, receive, or log in. One user said the disruption had brought their department "at a standstill."
Microsoft had not yet responded to the outage reports or provided an explanation for the issue. What caused the disruption and when it will be resolved remain unknown.
