One thing to note is that the terms of the SLA are subject to change. The monthly uptime percentage can be calculated with the following formula:

вЂCalculated by taking the total number of minutes in a calendar month multiplied by the total number of users minus the total number of minutes of Downtime experienced by all users in a given calendar month, all divided by the total number of minutes in that calendar month multiplied by the total number of users.вЂ™

The 99.9% is calculated as a вЂMonthly uptime percentageвЂ™. Microsoft defines вЂDowntimeвЂ™ as вЂany period of time when users are unable to send or receive email via all supported mailbox access which is calculated using Exchange application availability in database minutes and combined data where applicable from server, operating system, application, network segments and infrastructure services managed by MicrosoftвЂ™. But what do the terms вЂuptimeвЂ™ and вЂdowntimeвЂ™ actually mean in this context, and how are they defined? Simply, the SLA offers that if the services that you have subscribed to are not available for 99.9% of the time, you will be financially reimbursed.

So all business owners who utilise Office 365 for their organisation can sleep soundly at night, safe in the knowledge that Microsoft has promised them their services will be available 99.9% of the time, and in the case that Microsoft does not meet this promise, they will be financially reimbursed.Д«ut do these business owners really know the details of this promise? Have any of them even read the SLA provided by Microsoft? Most have probably seen the marketing material offering this promise and took it at face value. So when Microsoft released Office 365 to market, it was offered with a 99.9% financially backed uptime guarantee. Microsoft acknowledged that a potential move to the cloud made businesses wary of not having control over their Email Servers and therefore, not being able to influence uptime and availability of services.
