 - The account that you use to connect must be enabled for PowerShell. For more information, see [Enable or disable access to Exchange Online PowerShell](disable-access-to-exchange-online-powershell.md).
 
 - TCP port 80 traffic needs to be open between your local computer and Microsoft 365. It's probably open, but it's something to consider if your organization has a restrictive internet access policy.
