Protecting your information and staying compliant with Microsoft Teams

AlexMags : Hi and thank you for the suggestion, i think it's a valid ask. I looked through our Teams UserVoice and didn't find this specific request, but I found a similar one. Sharing in case you want to add your or vote. I know this alternative doesn't solve your problem from the root, but most support centers that use either phone, chat, or bots for support provide a default message stating that the conversation is being recorded for X purposes. 

willie19691123: In addition to what Adam jus shared, you could also check our docs for question #1. For retention policies, as explained in our documentation: by default, Teams chat, channel, and files data are retained forever. As an admin, you can set up Teams retention policies for chat and channel messages and decide proactively whether to retain the data, delete it, or retain it for a specific period of time and then delete it.
