Call URL Handler leads to crash in new Teams
I have a problem with an application which we are developing. This happens only in the new Teams Application. Basically I need to start an external Program, which is registered in Windows with a...
I tried with all suggested ways.
All of them do not throw any error anymore.
But it's not working. It looks like as if the new teams app is not passing non-standard url handlers to the operating system. So something standard as tel: is working, and the registered application is called, but not those we are using for our application (which are also correctly registered in windows and work if called from a browser).
With the old Teams everything is working as expected.

We’ve had an allow list in place for both T1 and T2.1 desktop clients for a while now. These lists are aligned so any protocols which worked in T1 should also work in T2.1. You can find the current allow list here:
