some within impacted services such as Outlook Room Finder.
The company adds that it is “continuing to see improvement in service availability, but some users are still
experiencing impact. We're restarting the infrastructure that serves user requests, to resolve the remaining impact and fully restore service.”

residual impact for Outlook on the web. We're investigating the underlying cause of this suboptimal service health so we can ensure all users' Outlook on the web functionality is restored.”
