Capture actions of script

Hello Tech gurus,

I have a script which disable forwarding applied on users:

Get-mailbox $_.alias | Where {$_.ForwardingAddress -ne $null} | Set-Mailbox -ForwardingAddress $null -DeliverToMailboxAndForward $false }

Can you please help me in extracting actions of script into outfile.log/.txt.

I would like to know if it is disabled for every user.

I thank you in advance for your assistance and guidance.

regards,

Gautam
