Frequent errors and how to fix them

The term 'Connect-ExchangeOnline' is not recognized
Install-Module ExchangeOnlineManagement; new window; Import-Module ExchangeOnlineManagement.
A window handle must be configured / MsalClientException
MSAL/WAM handler bug: no window for sign-in. As admin: winget install --id Microsoft.PowerShell --source winget, then pwsh. ISE still runs 5.1 and can load the module; use Connect-ExchangeOnline -DisableWAM there. Unattended: certificate or managed identity. Full explanation.
Error Acquiring Token: System.NullReferenceException / 0x80070520
WAM sign-in (3.7.0+) failed. NullReferenceException: another module (usually Graph) loaded a different MSAL version; new window, Connect-ExchangeOnline first, or -DisableWAM. 0x80070520: PowerShell runs as another account or in Task Scheduler. Full explanation.
WinRM / CreateExoPSSession
Use V3+ (REST). No separate WinRM session.

Interactive: MFA. Scripts: certificate + Exchange.ManageAsApp, not a password.
Unauthorized / Access Denied
Exchange Administrator (or a tighter role) on the user or service principal.
