Starting at 2:30 p.m. EST Today, Office 365 users across the United States are finding it difficult to access Outlook and use Microsoft Teams, with active calls dropping.
When trying to connect with accounts on Microsoft 365, users received the "Something went wrong" alert and other error messages.
«Users may have an impact on Microsoft Teams, Outlook, SharePoint Online, OneDrive for Business and http://Outlook.com,Microsoft explained.
"We have received user impact reports on Microsoft 365 services and are working to investigate the cause of the problem," Microsoft said on the 365 service status page, adding that "any user can see an impact on this issue."
Earlier today, customers also reported problems accessing the Microsoft 365 Admin Center.
"We've detected and restarted downtime management center service components to reduce the impact," Microsoft said two hours later.
«Our telemetry shows some improvement in service, although administrators may still see delays when using the management center. "
Last week, Office 365 suffered another outage in the United States and Australia, which prevented users from logging in to Microsoft Teams, Office.com, Power Platform and Dynamics365 accounts.
According to a preliminary post-incident report released by Microsoft after the incident was resolved, the reason for last week's outage was a service update for Azure AD that accidentally affected the production environment and caused service availability to deteriorate.
