@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?

Script stopped working and shows errors

Uncaught TypeError: Cannot read properties of undefined (reading 'ownerDocument')
and TypeError: Cannot read properties of undefined (reading 'ownerDocument')

Here is an updated working version of the script as of 17/07/2023:

Hello everyone.
Script does not work with New Teams. The option to go back to Old Teams is not available anymore. Can the experts revise the code to work with New Teams?
Regards!
