first of all I wanted to ask you why is the Teamviewer page so bad? We need to use the old IE11 to get the page working. This is really bad!
Nontheless I want to import and export users using the CSV files and powershell. I already took a lot here, and also on the KB. No luck. Also I was looking at https://integrate.teamviewer.com/en/integrate/usermanagement/
Is there somwhere an stepbystep guide? Would be nice to get help here.
