How to set up forwarding from a number of corporate addresses to addresses in another domain (the names will remain the same)?

Question

Mail server

Now the users that will need to be redirected are in the same security group in AD. The domain will change to a similar name, in fact it was [email protected], and it will become [email protected]

I saw something similar in How to create mailboxes in bulk and set up redirection for everyone? . But I have a question, how to do this without throwing all the addresses into one OU, namely from the security group. Well, what command, as I understand it, can be done through
Set-Mailbox [email protected] -ForwardingAddress [email protected]
and through
Get-User.

How is it better?

Answer 1

Get-User -Filter {MemberOfGroup -eq } | Set-Mailbox...
So it's not necessary to throw addresses into an OU or a security group - a file with a list of addresses is enough, then you transfer this list by pipeline to Set-Mailbox.
