Be sure to disconnect the remote PowerShell session when you’re finished.

To disconnect all currently open PowerShell sessions in the current window, run the following command:

Get-PSSession | Remove-PSSession

How do you know if this worked?

After Step 4, the Exchange Online cmdlets are imported into your Exchange Online Remote PowerShell Module session and tracked by a progress bar. If you don’t receive any errors, you connected successfully. A quick test is to run an Exchange Online cmdlet, for example, Get-Mailbox, and see the results.
