Hey guys! Ever run into the frustrating issue where a SharePoint Online web part just vanishes when viewed in Internet Explorer 11? Yeah, it's a head-scratcher, but don't worry, we're going to dive deep into the common causes and how to fix them. This guide is your ultimate resource for getting those web parts back where they belong, ensuring a seamless experience for all your users.

Understanding the IE11 Challenge with SharePoint Online

So, you're facing the dreaded SharePoint Online web part missing in IE11 issue. This is a fairly common problem, and it usually boils down to a few key factors. Internet Explorer 11, while still used by some organizations, is an older browser and doesn't always play nicely with the latest web technologies. SharePoint Online, on the other hand, is constantly evolving, incorporating new features and standards. This can sometimes lead to compatibility issues, especially with custom web parts or older code.

When we talk about SharePoint Online and Internet Explorer 11, we need to consider a few critical areas. First, IE11's support for modern JavaScript and CSS standards is limited compared to newer browsers like Chrome, Edge, or Firefox. This means that web parts relying on these newer technologies might not render correctly or at all. Second, IE11 has specific security settings and configurations that can impact how web parts load and function. Things like ActiveX controls, mixed content restrictions, and caching can all contribute to the problem. Finally, compatibility view settings in IE11 can sometimes interfere with SharePoint Online's rendering engine, causing web parts to disappear or display incorrectly.

Let's dive a bit deeper into why these issues arise. Think of it like this: your web part is a finely tuned engine designed to run on a modern racetrack (SharePoint Online). But IE11 is like an older car that might not have all the latest upgrades. Some parts might fit, but others might need adjustments or simply won't work. This is why understanding the underlying technology and potential conflicts is crucial to resolving the problem effectively. We'll explore specific troubleshooting steps and solutions in the following sections, so keep reading!

Common Causes of Missing Web Parts in IE11

Okay, let's get down to the nitty-gritty. Why are your web parts not showing in IE11? There are several usual suspects, and figuring out the culprit is the first step to fixing the problem. Here are some of the most common causes we've seen:

  • Browser Compatibility Issues: As we discussed earlier, IE11's age can be a major factor. It simply doesn't support some of the modern JavaScript frameworks and CSS features that newer web parts might be using. This can lead to rendering errors or complete failures.
  • Compatibility View Settings: IE11 has a feature called Compatibility View, which forces the browser to render web pages as if they were designed for older versions of Internet Explorer. While this can be helpful for legacy sites, it can wreak havoc on SharePoint Online, causing web parts to disappear or display incorrectly. Compatibility View settings are often a major pain point.
  • Add-ons and Extensions: Sometimes, browser add-ons or extensions can interfere with SharePoint Online's functionality. These add-ons might be outdated, poorly coded, or simply incompatible with SharePoint's scripts. They can block web parts from loading or cause unexpected behavior.
  • Security Settings: IE11's security settings are quite strict, and they can sometimes block necessary scripts or content from loading. Things like ActiveX controls, mixed content restrictions (loading HTTP content on an HTTPS page), and overly aggressive security zones can all contribute to the issue.
  • Caching Issues: An outdated or corrupted browser cache can also cause problems. IE11 might be trying to load an older version of a web part or script, leading to errors. Clearing the cache can often resolve these types of issues. Clearing the cache should be one of your first troubleshooting steps.
  • Custom Web Part Code: If you're using custom-developed web parts, there might be issues within the code itself. Errors in JavaScript, CSS, or the web part's manifest file can prevent it from loading correctly in IE11. Custom web part code needs to be thoroughly tested across different browsers.
  • SharePoint Online Updates: Occasionally, updates to SharePoint Online itself can introduce temporary compatibility issues with older browsers like IE11. Microsoft usually addresses these quickly, but it's something to keep in mind.

Understanding these potential causes is half the battle. Now, let's move on to the exciting part: how to actually fix this thing!

Troubleshooting Steps to Restore Missing Web Parts

Alright, let's roll up our sleeves and get those missing web parts back in action! Here’s a step-by-step guide to troubleshooting the issue, covering the most common solutions:

  1. Check Compatibility View Settings: This is often the first and easiest thing to check. In IE11, press Alt to show the menu bar, then go to Tools > Compatibility View settings. Make sure your SharePoint Online site isn't listed in the
