So, I'm in one of the sovereign MS365 cloud instances and we are transitioning from Skype for Business online to Teams. in the Teams Upgrade window there is a "Notify Skype for Business users that an upgrade to Teams is available" switch. When it is turned on, Skype displays a blue banner at the top with a "Try it" button. With the "Download the Teams all in the background for Skype for Business users" switch turned on, if a user clicks the "Try it" button before the client install has been downloaded to their machine, it will launch a browser and send the user to the public teams site (teams.microsoft.com). This will cause an error when the user tries to login. Is there any registry or file that can be changed to cause the 'Try it" button to redirect the user to the appropriate sovereign cloud's URL?
