- Extract messages id 
  On Google Chrome developper tools :
   copy(id.join("\n"))
   
Delete a message, copy the ajax request and export as CURL (bash) (on network tools maybe end by "softDelete")

On notepad ++ on replace regex mode 

REPLACE (.*)
Your CURL shell command find the id curl 'https://emea.[...]/121545326566?behavior=softDelete by $1 like this 'https://emea.[...]/$1?behavior=softDelete

lauch on linux terminal all lines 
*/

Good idea

What do you think is it possible to remove the messages one by one directly after the ID collection? in the chrome development tool. (without curl)

Yes sure, use "copy as fetch" see https://stackoverflow.com/a/29832996 and modify ID on the fetch request

Good idea, I tried but I failed. Not clear for me how can i replace the message id inside of the fetch

fetch("https://amer.[.........]messages/1621243840520?behavior=softDelete", { [.........]});

and not clear where can I insert the fetch into your code.

Just after window.id.push(_id.substr(1))

Add your fetch.. and replace your 1621243840520 by "+_id+" but i don't think is good way to do that... Because you will have multiple query in the same time but test it

Just after window.id.push(_id.substr(1))

Add your fetch.. and replace your 1621243840520 by "+_id+" but i don't think is good way to do that... Because you will have multiple query in the same time but test it

I tried after window.id.push(_id.substr(1)) the fetch with an ID and it was okay but if I use "+_id+" it can not functional.

fetch("https://amer.ng.[...]/messages/"+_id+"?behavior=softDelete", {

I used copy(id.join("\n")) because I would like to see what contains the id. I see this:
essageBody
1621229710883
essageBody
1621229710994
essageBody
.......

Is there a problem with _id?

oh yes! is an error use :

if(i!sNaN(_id)){ //will check if _id is number
fetch...
}

I tested it, It can functional BUT in a short time I receive DELETE https://amer.[.......]messages/1620283331183?behavior=softDelete 429 error. So it is too fast. I tried several method for slow down the script but I couldn't.

Hi,did you solve the problem of sending reqests too fast?

I disabled the automatic scroll up and I use my scroll button of the mouse to move up the window manually. In this case I can manipulate the speed. anyway: I use a VAR with the message IDs and I never try to remove 1 ID twice -> lower number of error..

Hello,

Obviously it correctly selects my message in a red frame!
what should I do to remove them now?
Thank you

Edit ; Ok i have List id of all msg and now ?

Hello. This code should work today (October 2021) and automatically delete messages. Tested on Firefox. Just open Teams, select conversation, and run this code from the Console, it should delete all your messages in the currently selected conversation.

It should only scroll up, so if you want to only delete messages older than X, just scroll to date X and run the script then. However this is not 100%, it may delete more. Always expect all your messages might be deleted.

IMPORTANT: Do not enter the browser window while it is running. The code simulates mouse movement and clicks, you would interfere with it.

(function() {
	var queue = [];
	var last_processed = (new Date()).getTime();
	var loading = true;
	var repeat = setInterval(function() {
		if(loading) {
			if($("div.pending").size() == 0) {
				loading = false;
				jQuery('#page-content-wrapper').find('div[id^=m].self').each(function() {
					var id = $(this).attr('id').substr(1);
					if(isNaN(id)) return;
					if($(this).attr("data-tid").indexOf('tombstone') != -1) return;
		
					queue.push(this);
					$(this).css({'outline': '5px solid #000'});
				});
			}
			else return;
		}

		if(queue.length > 0) {
			var item = queue.shift();
			$(item).css({'outline': '5px solid #cc0'});

			// cleanup of possible leftover mess
			if($("message-actions").size() > 0) {
				$("[id=messageBody]").trigger("mouseout");
			}

			console.log("Delete ID " + $(item).attr("id"));
			$(item).find("#messageBody").trigger("mouseover");
			setTimeout(function() { $("message-actions button.message-actions-more").trigger("click"); }, 500);
			setTimeout(function() { $("div#messageActionDropdown button[track-summary=Delete]").trigger("click"); }, 1000);

			last_processed = (new Date()).getTime();
		}
		else {
			$('virtual-repeat').scrollTop(0);
			loading = true;

		if(last_processed < (new Date()).getTime() - 15000) {
			// if no new messages are coming up for 15s, consider it finished

Thanks a lot ! 🙏 The last script is working fine ! 👍

Something has changed and the code doesn't work. Could you check it, please? :)

Sorry, can someone make a video of the whole procedure? I can't get it to work :(

Hi, any chance you could look at the code again? It initially deletes messages but it does not scroll up and goes awol after the first batch. Tested on Chrome and Firefox. Thanks for any tips.

Hi, thank you for the script. I'm having the same issue as breakthefunk here. It starts deleting messages and stops after a few messages. Doesn't scroll up either. Could you please update it? Thank you so much.

@sadagst BRILLIANT !!! Unfortunately you have to scroll with the mouse so that the script does not hang

But still best solution I found on internets

@Endeer could you please update your script? it doesn't work anymore. it marks some messages, but no right click and no delete anymore.

Hello everyone,

I have adapted the script and it is working now (27-OCT-2022). They changed .ui-chat__message__content to .ui-chat__messagecontent.

		evt.initMouseEvent(which, true, true,
			element.ownerDocument.defaultView, 1, 0, 0, 0, 0, false,
			false, false, false, 1, null);
		
		element.dispatchEvent(evt);
	}

	var repeat = setInterval(function() {
		if(loading) {
			if(JQ.find("div.pending").size() == 0) {
				loading = false;
				JQ.find('div[data-mid]').each(function() {
					var id = $(this).attr('data-mid');

@Zegorax it works. thank you very much!

Hello @Zegorax
First, congrates to everyone. This code is awesome to stop Microsoft abuse. I know people that lost hours by month to delete message by message on teams.
i think update (27-OCT-2022) is not working. Several times does not scroll, It freezes, its gives errors of HTTP 429 Too Many Requests, it has irregular behavior. It deletes messages that appear latter. Tested on EDGE and Chrome

Improvement in two directions: it scrolls up as it meets the elements, and it skips over those that are not to be deleted faster. It still may stop here and there especially if some of the messages are very big, but either zoom in or nudge with the mouse. Good thing is that if you switch from one chat to another it will seemingly start deleting the messages in other chat too. I had probably thousand of messages and it worked quite well and finished that many messages in less than 20 minutes. Sure you will get too many calls occasionally but I would just refresh the screen, start the script again and it would delete if any message was not deleted yet. Taking into account what this script does and how it does it, I do not think that you can expect deleting more than 1 message per second. And this one with a hiccup here and there is doing just that.

     var JQ = jQuery("iframe").contents();

@alexpeter-pen lots of thanks but is to fast on delete. 429 (Too Many Requests) errors on many messages. its seems that deletes but does not delete. they appear again on refresh. To protect Microsoft Teams and its users, the bot APIs provide a rate limit for incoming request https://learn.microsoft.com/en-us/microsoftteams/platform/bots/how-to/rate-limit
can you please resolve it? i've tried to put a code to slow script but no lucky, i think ive only delayed the start.

@geoginho I think I explained it in my comment about the rate limit, what is actually happening. I had to go twice about it over the same chat. But it is still faster than the initial solution overall and more reliable. If it bothers anyone the only way to try fixing the rate limit is to increase 1000 to something higher, but even then there is no guarantee that it will not happen.

@alexpeter-pen cool! its was easy than the solutions i was looking. its is running on 5 minutes and without messages of rate limit. i've changed 1000 to 2000. I have 3 years of messages and rate limit bothers a lot because i have to restart a 20 or 30 times from the beginning to try do delete messages that cannot be deleted before. Now on 2000 it is running and deleting all. Many thanks!!! Ops. To many requests now. I think that has a limit on total of deletes. Refresh and start again and here he goes more 5 minutes without any errors.

This is great, thanks. Does anyone have something similar for Skype?
