If you are experiencing problems with an Office 365 service, the native option is to check Microsoft’s Service Health Dashboard (SHD) in your Microsoft 365 Admin Center to determine whether this is a known issue with a resolution in progress before you call support or spend valuable time troubleshooting. However, the information that is provided through the SHD is only of limited use, as it focuses primarily on the overall service health instead of tenant-specific or user-specific problems.

The Office 365 Domino Effect

Jeff Guillet (MVP, MCSM) & Justin Harris (MVP, MCSM, MCM)

Over the last several years Microsoft has made tremendous headway in showcasing the value proposition of the Office 365 platform and suite of collaboration tools. In fact, the argument can be made that the Office 365 suite of tools has helped fuel the team-based way of working. A recent report shows that 80% of your time during work hour is spent collaborating like conference calls or meetings.1  McKinsey sheds additional light on this increase in collaboration by stating that 45% of workers are using social technologies to accomplish daily tasks2.

There are a couple of deeper issues here that warrant a closer look to understand what the real risk is, and what you can do about it.

As reported earlier, Office 365 was recently hit with a widespread issue. According to the case details that Microsoft posted to its service dashboard, the problems started around 6:15 PM (EST) on July 15 and were solved by July 15 at 9:30 PM (EST). 

That is a little over three hours that customers were experiencing all sorts of issues! Even though it's unlikely this outage alone will affect Microsoft's 99.9% uptime on a yearly basis, the impact and inconvenience on the customer base is big. While Microsoft does a terrific job running Office 365, this wasn't the first outage, and it likely won’t be the last, either.
