If you encounter the prompt to update, with the added clarification of "Please contact your IT team to update your app", you likely do not have the necessary permissions to update the app yourself or have had a version installed that requires IT assistance. 

If you do not have an IT team or this is a personal device, then this error may be due to a misconfigured installation or issue during installation including:

• The device was managed by an organization when Zoom was installed but is no longer managed.
• The auto-update MSI flag or auto-update plist item was enabled during installation.
• You are currently running a version below the minimum version allowed by Zoom per our quarterly global minimum version enforcement.

What is a managed device?

A managed device is any device that has been given to by your business or school organization. A managed device can also be any device purchased by you, but has a managed work profile. 

How to resolve this error if your device is managed by your organization

Zoom recommends contacting your IT organization if the device is a managed device or has a managed work profile, even if you have administrator privileges on the device. 

If you need to join a meeting immediately, then the Zoom Web App can be utilized until the standard Zoom application can be updated.

How to resolve this error if your device is not managed by an organization

If your device is not currently managed by an organization, and you are receiving the error message "Please contact your IT team to update your app" when trying to update your device or when trying to join Zoom Meetings or Webinars, then Zoom recommends uninstalling and reinstalling the Zoom Application.

If you are having issues uninstalling or reinstalling, ensure that you are logging in with credentials with administrator privileges on either your Windows or macOS device.
