I transferred all my skype chat etc. into Teams as instructed, which worked well until yesterday, now my chats and contacts have disappeared and I'm getting information about signing me up and it appears Teams is connected to Microsoft 365 which I don't want. I have Office 2013 because I have older Office files which are essential to be able to open and only 2013 on Windows 10 will do that.
How can I get my Teams chats etc. back. They include conversations with my son who developed the website for our club. He has passed away and I need to refer to chats because there is information about the club website which I need to operate it.
