Microsoft Exchange Online outage affects Outlook web users

Two weeks ago, Redmond linked a weekend Microsoft 365 outage impacting Outlook and Exchange Online authentication to a "code issue." A subsequent advisory revealed that users still experienced issues accessing calendars and email messages using the iOS native mail app. ​The company has also partially mitigated a week-long Exchange Online outage, which is still causing delays and failures when sending or receiving email messages. Initially tracked under EX1027675, this ongoing issue is now tagged as an incident with nearly identical impact under EX1030895. While the company has yet to share more information on the regions impacted by this incident, it has been tagged as a critical service issue tracked under EX1036356 on the Microsoft 365 Admin Center and says that affected users may see "Something went wrong" error messages. Microsoft is also investigating a separate incident (EX1035922) caused by a code error in a recent update that prevents some Exchange Online users from searching using Outlook on the web or the new Outlook client. ​Microsoft is investigating an ongoing outage preventing Outlook on the web users from accessing their Exchange Online mailboxes. "Affected users may see the following error message 'We didn't find anything, try a different keyword' when performing searches in Exchange Online," Microsoft explains. According to thousands of user reports on DownDetector, the issue started impacting Microsoft's services more than two hours ago and is affecting customers attempting to log into their accounts, accessing the website, and triggering server connection problems.
