PowerShell - Your browser is not supported

Question

I'm trying to do some work using the ExchangeOnlineManagement PowerShell module. Once the module is installed, the first step to do is connect to the service using Connect-ExchangeOnline. And that launches the authentication box. The problem is that, once I authenticate, I get a message saying

Your browser is not supported or up-to-date. Try updating it, or else download and install the latest version of Microsoft Edge.

The thing is, I AM using the latest version of Microsoft Edge. So I don't know what to do here.

Answer 1

I don't think so. Actually, in investigating it further, it seems that the cmdlet Connect-ExchangeOnline calls IE explicitly. Why do I say that? Because on the multiple systems I've tried this on, including a Sandbox, just to try it, even though the default browser is set to something else the authentication call opens IE, and that browser is, in fact, not supported.

Interestingly, I was able to open the authentication in Edge. Then, when I killed the auth session in PS, and re-ran the cmdlet, it came up with the authentication box (in IE again), but this time recognized that I was already signed in, and I was eventually able to get the connection.

But the bottom line is that I shouldn't have had to work so hard. This is not an Exchange issue, per se. It's a PowerShell issue. It's an authentication issue. But this is before we actually get to Exchange.
