Since Monday morning, users have been experiencing problems when they want to work with Exchange Online and Microsoft Teams. Microsoft now seems to have found the cause of the problem.
Due to the outage, users can no longer search within Outlook. Other functions, such as sending and receiving emails, still work. In addition, the calendar in Microsoft Teams does not work as well. For example, it can be difficult to open calendar entries. However, video calls via the platform remain possible.
Microsoft is investigating the cause of the outage and has since found a possible explanation. Just after lunch, the company provided an update: “We’ve identified a recent change which we believe has resulted in impact. We’ve started to prevent the change and are investigating what additional actions are required to mitigate the issue.”
The number of people affected by the outage is now minimal. Microsoft has indicated that there is some delay in the solution. However: “The patch has deployed 90 percent, and according to telemetry, service availability is recovering. An estimated time to completion of the fix is not yet available.”
