Over the last few months Microsoft Teams has been making a great impact! It’s been awesome to see an application that gives you the call and video functionality of Skype for Business and the collaboration strengths of SharePoint together with integration options with other application.

Over the last few days however there has been quite a lot of trouble with Microsoft Teams. Just to give a bit of an idea of the impact that faulty Channels in teams has, here is one of the conversations on Tech Community.

So how do you troubleshoot Teams.


The magic key combination is: Ctrl – Shift – Alt – 1

Well that is the easy part!


I’m not going to try and understand all the messages here, but there seem to be two parts to this file.

First there is a bit of json formatted text:

"userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Teams/ Chrome/58.0.3029.110 Electron/1.7.1 Safari/537.36",

"versionHash": "aff87a541c1617faad141e6d6ee80aea44b9505b",
"clientVersion": "27/",

"views": {
"0@": {
"templateUrl": "components/middle-messages-stripe/middle-messages-stripe.html",
"controller": "MiddleMessagesStripeController",
"controllerAs": "middleMessagesStripe"

This is followed by lines that have a time stamp, an message level and a message.

The message levels that I have seen are:

  • War : Warning
  • Err: Error
