Turn off Teams Preview by Default

[VNJoe]

The world is NOT your beta testers. We have clients who need reliable phone systems, and pushing Teams Preview out by default and overwriting our very clear and specific requirements to stay in channel is a very unscrupulous way to create a whole bunch of beta testers that have their own work to do.

You should never override the will of the customer at your discretion. This is irresponsible behavior. These are business phone systems that need to be reliable, something that seems to go ignored at Microsoft because it's considered some cool new toy that people don't pay for when they most definitely do.

This has to get turned off by default.

@VNJoe You have complete control, by default if you deploy a preview version of Office Apps, Teams will follow, but you can control that with the Teams Update Policy. Users can switch in and out of Public Preview from the About menu.

Also to add, Public Preview isn't beta testing, it's as it states a preview of what will become generally available in typically 4-6 weeks. Lots of real testing is done by Microsoft and key customers before Public Preview.
