Re: "The paramter is incorrent" error in new Teams client (VDI)
MTU42 Hey Guys, I've been trying to debug this this for WEEKS. At some point I certain that I've had surfed EVERY page on the web, but nobody came up with a fix that solved this problem in my envoiroment . Finally, just today, I managed to solve the problem for good. My Users got exactly this error when tying to start the New Teams Client: We are using a Remote Desktop Session Host envoiroment (RDSH, a.k.a. Terminalserver, operating on Windows Server 2022 (but I had the same error prior the InPlace-Upgrade on Server 2019), however we are NOT using FSLgix, like a hundred other buddys i found out there on the web, trying to solve this problem (apperantly they solved their problems by upgrading FSLogix). My solution may sound stupid, but works 100% for two ADs that i manage. So... "If it's supid, but it works: It ain't stupid" 😉 In the end, the problem was caused by a GPO. I was able to solve the issue by adjusting this user-trageted GPO: User Configuration > Preferences > Control Panel Settings > Internet Settings > Internet Explorer 10 > (Tab: General) > (Section Browsing history) > Settings. Here, my users hat an alternative path for their TEMP-Files: I updated this setting by removing the path and leaving the setting blank: I saved the GPO and as soon as my users logged in, the New Teams Client started like nothing ever happened. Surely, I didn't go for this setting in the first place, but I found out that RDSH-Users without GPO could start the New Teams Client, users with a GPO assigned could not. So I narrowed it down, by cloning my PROD-GPO, assigning the Clone to a test user. Then I removed GPO-settings from the Clone bit by bit until I had a working New Teams - until finally, I narrowed it down to THIS specific setting. I have no idea, why this setting is responsible for causing the problem, but after weeks of frustration, I only care for the problem to be finally fixed. All my >250 RDSH-Users are able to use the New Teams Client now. EDIT: For everyone who is facing the same problem: My problem might have been caused in the first place by a registry setting, that we had in one of our user GPOs. This Registry-Setting is basically the same like the Internet Explorer 10 setting mentioned above. So if your system has the same issues like mine, it's work checking this setting too: User Configuration > Settings Registry
