Exchange 2013 restricts sending and receiving email

People who do IT often encounter business needs, such as suspending an account and restricting someone's mailbox, that is, people who are restricted take severance compensation. Every time I receive such a demand, countless envy, jealousy and constant hatred will rise in my heart. When will it be my turn?

Today, I received a demand that a user can only send and receive mail from the organization. Hundreds of degrees have looked for it. There are two options, one is to change the restriction in the user's mailbox properties, and the other is to make a fuss on the sending connector. I don't have permission.

Comrades, as far as IT is concerned, it has to be Powershell, ah, a very simple little thing.

As a chicken thief, use an order first.

Get-Mailbox-Identity | fl *

Mainly look at an attribute:

Hehe, change it to $true.

Set-Mailbox-Identity domain account-RequireSenderAuthenticationEnabled $true

Then take a look at it again.

Ha ha, finished.
