How to resolve “Error initializing application. Error: ***Manifest not found for component id [guid].” when adding an SPFx webpart to Teams?

This article describes one way to fix the issue, where uploading and sideloading an SPFx webpart in Microsoft Teams just brickwalls you with a fairly non-descriptive error, and no way to proceed.

You can even find it from Teams extensions, but while adding it as a tab, you run into issues. Oh. That’s a bummer. […]

SharePoint-Teams -integration using a tab

This post describes one possible scenario for SharePoint-Teams -integration, how to achieve that, and what kind of issues there might be. Teams? What’s that? At Blue Meteorite, we at the Valo team have been leveraging Teams since early 2017 as our main communications channel. For us, it complements Yammer, email and Skype for Business quite nicely, although to be fair, it’s not always 100% clear which channel would be optimal for a certain piece of communication… :) The Redmond Magazine calls Teams Microsoft’s response to […]

Identifying IE11 compatibility mode in SharePoint

In this post, I describe how you can figure out if IE11 (Internet Explorer 11) has jumped in the compatibility mode. You run into this requirement every now and then, when trying to figure out some SharePoint browser compatibility mess-up. This is quite frequent, because in compatibility mode IE does its best to screw up your CSS.
