Do you often ask yourself the question –  Is there an Office 365 problem today? or how to troubleshoot Office 365?

While you try to find the answer, your customers (end-users) complain because they can’t access their business applications. Apart from all this, your boss needs an immediate status update. Trust me. It doesn’t feel great to be in that situation. And we know it.

Despite Microsoft claiming to provide 99.9% SLA, issues will occur with the Office 365 applications such as Teams, Outlook, OneDrive, Exchange Online, SharePoint, Yammer, etc. Often, the issues aren’t even Microsoft’s problems but ISPs or internal network change. There can be a lot of reasons (Network, OS, browser, personal device, upgrade errors, Internet, and much more), but which one is it?

Welcome to the hybrid way of working, where you have limited visibility outside your IT perimeter.

In this article, we will help you understand how and why you should better manage IT issues using some of these O365 troubleshooting tips.

8 Common and Known Issues with Office 365

As you already know, Office 365 is the go-to enterprise business productivity suite. According to Statista, over 1 Million companies worldwide are using the Office 365 suite. Believe it or not, 70% of those come from the US.

The following issues with Office 365 can arise when your remote end-users are working from home or office.

Don’t let IT burnout with Office 365 common issues
  1. Cloud Availability Roadblocks
  2. Performance Degradation
  3. Login Access and Timeout
  4. Synchronization Errors
  5. Network Jitter
  6. Bandwidth, Throughput, and Connection Problems
  7. Packet Loss
  8. Failed Program and Migration Update

As more employees connect to their favorite SaaS service directly through the Internet, you can expect to see more problems. (We hope not, though!) Hence, it’s critical to know if the Office 365 apps are performing well. The faster you identify and fix the situation, the sooner your employees return to a productive working digital experience.

Furthermore, we are compiling a list of past O365 outages that you might be already aware of.

  1. Microsoft Teams Outage on April 27
  2. Azure DNS Outage on April 1
  3. Microsoft 365 Outage on March 15
  4. Exchange Online Mail Delivery Outage on February 3
  5. Office 365 Outage on January 27
  6. Teams Outage on August 19 (2020)

Phew, a long list, isn’t it?

Five significant outages this year to date. And you might think to yourself:  Why are we telling you this?

That’s because, in all the above outages, we have successfully detected the problem 30 mins to 2 hours even before Microsoft acknowledged it on Twitter. When unseen and unplanned events like an outage occur, they bring new or compound ongoing IT investigations. As a result, end-users experience poor outcomes, and businesses suffer downtime losses. But, of course, I am assuming that you want to detect your next outage before it’s too late!

5 Steps You Can Take to Successfully Troubleshoot Office 365 Outages & Slowdown Issues

However, don’t let the thinking of an outage stop you. In spite of all the hurdles and rising flames in IT’s Kitchen, there is hope.

Below are troubleshooting steps that you must take to douse the fire.

1. Build Situational Awareness and Confidence with Proactive Notifications

No matter what monitoring tool you own, the responsibility to identify and resolve Office 365 performance issues rests on your shoulders. But let’s be honest. Would you want your customers or employees to reach out to you first or the other way? In other words, the days of being reactive are over; it’s the dawn of staying proactive and building some energy in the team.

Whether the issues lie with the provider (Microsoft), the LAN, or the end-user computing environment, make sure your modern tool discovers them before customers reach out to you.

Consequently, your team comes across as more intelligent as they know what they are doing.

2. Baseline Office 365 Application Performance Data

Ok, you’ve got the awareness. But is there a way to baseline your Office 365 app performance? So first, let’s get to that. Did you know that our enterprise customers (BCD Travel, Robert Half, Aetna, Intel, etc.) pride themselves on crowd-sourced data?

Why? Our unique crowd-sourced analytics expedite root cause analysis by comparing your network infrastructure performance data to the rest. Indeed, this leads to quickly discovering and resolving problems – internal or external – within your IT environment. More importantly, your team reduces the response time and successfully meets their performance goals.

Congratulations, you can now answer, “Does the Office 365 fault lie with us or with everyone?”

3. Gain Actionable Intelligence with Synthetics

In a recent survey done by us, 70% of our customer issues were found in the corporate enterprise network and not with the provider. This is the truth about monitoring with synthetics.

Personally, it would help if you had that visibility so that your team isn’t wasting their precious time blaming Microsoft. Instead, network admins can use real-time insights from synthetic monitoring agents to test ALL of the Office 365 apps actively. Most likely, the chances are that you can find potential bottlenecks (proxy, gateway, router, DNS, LAN/WAN settings) in your backyard with a hop-by-hop network path visualization.

And you can take rapid action.

4. Package Real User Monitoring Insights with Digital Experience Monitoring

Undoubtedly, including synthetics as part of your monitoring strategy is supercritical. However, that’s just one side of the monitoring spectrum for your team to be efficient.

And let’s be honest.

Although synthetics can reveal if an Office 365 service is available or not, it cannot tell about the end-user experience for that particular application. Additionally, remote employees have multiple Desktop and network applications installed on their laptops. Take, for example, Microsoft Outlook. Even though Outlook may be up, it may be performing slow or crashing. Therefore, your team needs real user monitoring (RUM) insights to successfully capture endpoint data (CPU, memory, disk, crashes) to assist knowledge workers better.

A Digital Experience Monitoring (DEM) solution combines the best of Synthetics and RUM in a single pane of glass. And in our experience, you need both – Better Together. Download our whitepaper.

5. Manage Office 365 Outages in ServiceNow

Apart from discussing synthetics and RUM, let us talk about managing service alerts and automated notifications.

Do you own any of the below ITSM/AIOps/ChatOps/ITOM/DevOps tools in your environment?

      • ServiceNow
      • PagerDuty
      • MoogSoft
      • Slack
      • Splunk
      • ScienceLogic
      • ManageEngine
      • SumoLogic

If your answer is a yes, you can connect a Digital Experience Monitoring tool to your favorite ticketing system and automate IT process workflows. By integrating 3rd party webhooks and APIs, your team can streamline and manage all incidents, including Office 365 outages, in a single view. Nevertheless, a DEM tool with its comprehensive operational dashboards should be sufficient for full-scale Office 365 troubleshooting.

So, you have reached this far. Great!

But wait, there’s more…
