Bulk MS Teams Message Removal is a free Chrome add-on developed by lihster.developer. As the name suggests, this tool allows users to delete Microsoft Teams messages in bulk, specifically in channels. Unfortunately, it does not currently support deleting messages in chats.

One of the standout features of Bulk MS Teams Message Removal is its ability to remove threaded messages. This makes it easier for users to clean up conversations and remove unnecessary clutter.

It's important to note that there are two different types of licenses for this add-on. Admin License allows Teams admins to delete other people's messages in channels, while Non-admin License only allows users to delete their own messages.

To use Bulk MS Teams Message Removal, users need to log in with their Teams login, get a license via Lemonsqueezy, and enter it in the extension popup. From there, they can select the target team, channel, and message sender whose messages they want to delete, and click on the Bulk Delete button.
