For Teams Go is making use of the native Microsoft Teams client for Windows and thus following all rules set by the IT/Teams administrator in the O365/Teams Tenant. Depending on the work processes within the organization, it might be useful to change certain default values. All information below is coming from the Microsoft support websites and might be subject to change. For the latest information, always check the Microsoft support website(s).
Note: Since CTOUCH support is not the IT/Domain administrator, we cannot help in making these settings. All settings needed are done within the Microsoft environment and should be handled by the IT admin with the required administrative rights.
