Downtime is defined as any period when end users cannot see the state of presence, conduct instant chats, or start online conversations There is no specific SLA for the “phone system” and associated PSTN services such as cloud-based auto-exchange and call queues. Microsoft provides service credits if the availability of the service is lower than Microsoft therefore offers a service credit that is charged to SLA for a monthly operating time of 99.9, which is a downtime of up to 43 minutes and 49.7 seconds per month before being injured. This is consistent with most other Office 365 services, which also offer a 99.9% SLA. Service Credits are your sole and exclusive remedy for performance or service availability issues under the Microsoft Agreement and SLA. Microsoft does not specifically cover Microsoft Team uptime or interrupt Office 365 service availability. However, you are talking publicly here about the office 365 up-and-running life as a whole. While Microsoft offers a top-notch guarantee for their service, they even exceeded their promise in the past fiscal year. In fiscal year 2013 (June 2012-July 2013), Microsoft`s actual global availability was astonishing 99.98%, 99.98%, 99.97%, 99.94%, and 99.97% per quarter for service. . . .
