Zusätzliche team- und kanalbezogene Funktionen und Probleme in Microsoft Teams for Business
Dear OG2000
Thank you for reaching out to the Microsoft Community! We are glad to assist you here.
Based on your description, when content is deleted in a Teams channel, the message will appear as "This message has been deleted" along with an undo button beside it. You want to permanently remove this message and the undo option.? Please let me know if my understanding is correct.
At present, there are no other methods to permanently delete the post including "This messaged has been deleted" notification and the undo button. Because in many cases some customers accidentally deleted it and want to undo the action to recover them, so our product developer put the undo button there as a solution. But your suggestion is also very useful and we appreciate for your valuable suggestion.
I highly encourage you to try giving feedback at Microsoft Teams · Community so our product development team can know your requirements for future product improvements.
If you have any other questions or need further assistance, feel free to ask
Best regards,
