In powershell 5.1: Connect-MgGraph timeout behavior regression in versions >= 2.35 (does not respect 2-minute timeout)

Describe the bug

We've observed a change in timeout behavior for Connect-MgGraph across different versions of the Microsoft.Graph PowerShell module. In our teams this behaviour is

In version 2.25:

• The expected timeout of approximately 2 minutes is respected.
• The account selection window (interactive login) closes correctly when the timeout is reached.

In versions 2.35 and later:

• The operation no longer respects the ~2 minute timeout.
• Instead, it fails after approximately 5 minutes.
• Additionally, the WAM account selection dialog does NOT close automatically when the timeout occurs.
• The dialog remains open indefinitely until manually closed by the user.

Actual behavior:

• Timeout occurs after ~5 minutes.
• WAM dialog remains open and must be closed manually.

This appears to be a regression compared to version 2.25, even though previously it was indicated that timeout behavior had not changed.

The WAM dialog not closing is a known issue?

If needed, we can provide additional environment details.

Additional context:

• This behavior has been reproduced across multiple machines.
• Several team members are experiencing the same issue, so it does not appear to be limited to a single environment or device.

Thanks

Expected behavior

• Timeout occurs after ~2 minutes.
• WAM dialog closes automatically.

How to reproduce

Run with 2.25 first and then with 2.37.0

$ini = Date
Write-Output "${ini}: Inicio"
powershell.exe -command {
    $tenantId =  "xxxx"
    Connect-MgGraph -ErrorAction stop -ContextScope Process -TenantId $tenantId

}
$fin = Date
Write-Warning ("Tardó: {0}" -f ($fin - $ini).totalminutes)

SDK Version

2.37.0

Latest version known to work for scenario above?

2.25.0

Known Workarounds

The workaround I found now is not working, sometimes connect-mggraph hangs

UPDATE: As 2026-07-02 with 110 seconds of timeout the workaround is working

With powershell 7 the behaviour is the correct (change powershell.exe to pwsh.exe)

### Other information

_No response_

Inizia riproducendo il comportamento con Connect-MgGraph in Windows PowerShell 5.1 usando le versioni del modulo 2.25.0 e 2.37.0, quindi confrontalo con PowerShell 7. La correzione è completa quando viene rispettato il timeout di circa due minuti e la finestra di dialogo di selezione dell'account WAM si chiude automaticamente; nell'issue non sono identificati file sorgente o test.
