How to deploy custom background images in Microsoft Teams 2.1

Microsoft will start soon to rollout the new Microsoft Teams client 2.1 and a lot of customers are asking how to bulk deploy customized background images to their clients. In the past, we could just copy our images to a dedicated Microsoft Teams folder and then we were good to go. However, with the new Teams client, this mechanism no longer seems to work. If you copy your images to the appropriate folder, the images will not appear in Microsoft Teams when you try to select your wallpaper. This blog post will show you a way how to handle and solve it.

[Updated] Auto dial with Microsoft Teams

I’ve released a blog post about auto dialing with Microsoft Teams in 2020. A user has commented that the tool AutoHotkey in Version 2.0 is not working any longer with my script. The script is written for AutoHotkey Version 1.0 and the publisher of the software changed the script language in the latest version. Therefor the user asked if I could write an updated script. For me, enough reasons to write an updated blog post about how to auto dial a phone number with Microsoft Teams.

How to find ownerless Microsoft Teams – Part 2

In my first blog post about how to manage ownerless Microsoft Teams, I wrote about the standard tools by Microsoft. In this blog post, I will give you some inputs how to use the Microsoft Graph API in combination with SharePoint Online and Microsoft Flow to find ownerless M365 groups and to stay informed about ownerless teams or Microsoft 365 groups.

I will use the Graph API to get a report about the existing Microsoft Teams. This dataset is filtered on ownerless teams and is written to a SharePoint list. When stored in the SharePoint list, you can extend the solution by triggering a Microsoft Flow to notify the service desk, for example.

How to manage ownerless Microsoft Teams – Part 1

In this first blog post of two, I will cover how to manage ownerless Microsoft Teams and Microsoft 365 groups using board tools from Microsoft. Ownerless Microsoft 365 groups or teams are quite common and often seen in the wild.

A few weeks ago, Martina Grom tweeted about a new feature in the Microsoft Admin Center to find these ownerless Microsoft 365 groups or Microsoft Teams. It allows active members to be notified by mail when the team, or rather the Microsoft 365 group, no longer has an owner. This tweet brought this feature to my attention.

I will show you this option and an alternative way to notify someone about ownerless teams, like the IT staff for example, by a scripted solution in a second post.

How to downgrade the Microsoft Teams module in your Azure Automation account

In this blog post I will give a short overview how to downgrade the Microsoft Teams module in your Azure Automation account. Why you should do this? Assume you have developed a solution for some Microsoft Teams automations. You are using the Teams PowerShell module in some of your scripts. After a few months running the solution very smoothly, you decide to upgrade the PowerShell module in your Automation Account. And from that time on, your scripts don’t work anymore. Microsoft updates version 2.3.1 to the current release and some command-lets or parameter changed. Of course, we can update our solution but it is better to get a working solution in a short period of time and to find a solution in a lab environment.
