Answer 1

Current version is broken, uninstall all versions you've got and go back to a previous one. (mine was on 3.5.1, went back to it and now it works)

Uninstall-Module -Name ExchangeOnlineManagement -AllVersions -Force

Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.5.1 -Force

Answer 2

I had the exact same issue the other day. I figured it was maybe a "just me" thing because I don't use the module very often and was using it inside a Windows 10 22H2 sandbox.

I posted about the issue on Reddit, see below:

https://old.reddit.com/r/microsoft365/comments/1h6tffz/exchangeonlinemanagement_powershell_module_bug_in/

I don't know the best way to complain about this issue to MS. The best method I figure is to "Contact Owners" in the powershell gallery: https://www.powershellgallery.com/packages/ExchangeOnlineManagement/3.7.0

And just now my coworker made me aware they had the same issue and shared this thread, so adding my couple cents.

Answer 3

Got it up an running again. Just go in your ISE and install the new PowerShell 7.5:

winget install --id Microsoft.PowerShell --source winget

after that, you are able to connect to exchangeonline again.

Answer 4

Hello, I've had the same problem and looked into this - I've written everything I found here.
https://david-homer.blogspot.com/2025/01/exchange-online-management-powershell.html

Looks like Microsoft makes it that interactive login windows need a parent window now (so they don't disappear behind your application). They have however used some archaic method to get the console window handle. Therefore if you're not in a console application (for example a .NET or other Windows application, or PowerShell ISE etc etc) there is no console window therefore it crashes. I've reported it on the PowerShell gallery.

Answer 5

I just encountered that same "Handle" message. Tried each of the steps here, including uninstalling the ExchangeOnlineManagement module(s)

in the end, opening the script in notepad, and doing the connect commands manually in PowerShell (not ISE and as Admin)

• set-executionpolicy unrestricted
• Import-Module -Name ExchangeOnlineManagement
• Connect-ExchangeOnline

The last line bare is important because i had been using the added "-ConnectionUri https://ps.outlook.com/powershell/" option.

i feel this may have been contributing to the error. Once i connected, was able to log in as admin, the rest of the script ran clean.
