Any version beyond 2.19.0 of the Microsoft Graph Powershell module is causing errors in various Graph commands

[AdamBlaumann]

Describe the bug

In the past months we've had several cases of our Microsoft Graph PS commands not working, for some of them we even opened Microsoft support cases.
We found that returning to version 2.19.0 of Microsoft.Graph always resolves the issue, but we can't stay on this version forever.

The Connect-Graph or Connect-MgGraph command is always executed successfully, but then certain Graph commands (from different submodules) run into a generic error message, which is always the same: "An error occurred while sending the request."

There is no further information provided, even if we run them in verbose mode.

I've began wondering if perhaps there was a change in how the module connects with the M365 tenant, and maybe we need to have our firewall rules adjusted.
Were there any changes after version 2.19.0 in how the module connects?
Is the connection using a different port? Different target IP range?

Expected behavior

The graph commands run without throwing an error

How to reproduce

1. Install version 2.20.0 or later of the Graph module on one of our Windows servers
2. Run Connect-Graph with a user account or service principal
3. Run a graph command that the user account or service principal has permission to run (example: Get-MgApplication or Get-MgUser)

SDK Version

2.20.0, 2.21.0, 2.22.0

Latest version known to work for scenario above?

2.19.0

Known Workarounds

Avoid upgrading from version 2.19.0

Hi @AdamBlaumann thank you for raising this issue. Could you please let us know which version of ExchangeOnline you are using and also share debug output of any cmdlet after connecting to graph.

Vertraulichkeitsstufe: Intern Hello Tim, All the debug outputs are empty after connecting to Graph. We have attempted using MS Graph with ExchangeOnline module versions 3.4.0, 3.5.0 and 3.5.1. ExO module 3.4.0 works fine with MS Graph 2.19.0, but upgrading either of those to a newer version is when we start having issues. Example of an error message when we tried to load both modules into the same PS session (Powershell version 5.1): _Import-Module : Could not load file or assembly 'file:///C:\Program Files\WindowsPowerShell\Modules\ExchangeOnlineManagement\3.5.1\netFramework\Azure.Core.dll' or one of its dependencies. The system cannot find the file specified._ But the original issue we reported here happens independently from the Exchange Online module version. I mentioned the ExO module as an observation, because when we use both at the same time, it references a file that I think is part of the Microsoft.Graph.Authentication submodule (despite the file path in the error message indicating it as part of the ExO module).

@AdamBlaumann you need to upgrade to EXO version 3.6.0. See related issue here #2803

[AdamBlaumann]

@timayabi2020 That is not our issue. I probably shouldn't have mentioned the Exchange Online Management module at all. I've removed the part of the problem description that had any mention of it.
The issue is encountered when using the Graph module by itself. We don't need to import or use the Exchange Online Management module to encounter the issue.

@AdamBlaumann please share the output of this command [System.AppDomain]::CurrentDomain.GetAssemblies() | Where-Object Location | Sort-Object -Property FullName | Select-Object -Property FullName, Location | Out-GridView so that we confirm if there are any assembly version conflicts loaded in the session.
