Disable Inbox Rules for Disable Users

Question

I have found that when our helpdesk disables an AD user account (terminated employee) that has an Outlook inbox rule to forward the email to an email address outside the organization, emails sent to the former employee are still forwarded to that outside
email address.  I would like to run a script each day that queries AD for all disabled accounts, removes any forwarding SMTP adresses, then removes all mailbox inbox rules.  I have been trying to use get-aduser against a DC and export the list of
disabled users, this works fine.  I then take that csv, import it and use -foreach-object to set the forwarding smtp address to null.  I would then like to use the same csv file to run the -removeinbox rule command against the list.  I am having
a hard time time combining the commands I need into a PS script that works against both AD and Exchange.
Anyone have some powershell kung fu to assist me?  Thank you!

Hi Eric,
According to your description, I understand that you want a script to get a list of disabled AD user, then removes any forwarding SMTP addresses, then removes all mailbox inbox rules.
We can run following command to get a list of disabled AD user in PowerShell:
Get-ADUser -Filter 'Enabled -eq "false"' | select name,userprincipalname
More details about “How Can I Get a List of All the Disabled User Accounts in Active Directory? “, for your reference:

Also, run below command to disable forwarding SMTP address and inbox rule:
Get-Mailbox  -Identity xxxx | Set-Mailbox -DeliverToMailboxAndForward $false
Get-InboxRule –Mailbox xxxx | remove-InboxRule
However, we recommend use this disable AD user to disable mailbox.
By the way, this question will related to the script of Exchange server, please contact relevant team so that you can get more professional suggestions. For your convenience:
