Hi @BmoreOs ,
For question 1 and 2, totally agree with the replies provided by michev.
Regarding the 3rd question about chatting with everyone in the company, if the users in your organization is less than the limitation 250, you can refer to the steps below to create a chat for all users in one go:
- Prepare a member list which includes everyone. You can get this by exporting the membership of a distribution group that includes all using Exchange powershell, or assuming you have an org-wide team in Teams, you can export the member list via Teams admin center:
- Open the file in Excel, convert the email address column into a comma separated row. You may refer to the methods shared in the link below to prepare the email address list:
