Send As permission, also known as SendAs permission, gives a user permission to use another recipient's e-mail address in the From address field. For example, when you give the user Chris Send As permission on the mailbox of a user named Michelle, Chris can send e-mail messages that appear to be sent by Michelle, with no indication to the recipient that anyone other than Michelle sent the message. Or, if your organization uses a Help Desk distribution group, you can give Help Desk staff Send As permission on the Help Desk distribution group. That way, replies to messages sent to the Help Desk group appear to come from the group instead of an individual Help Desk technician.
Multi-tenancy deployments can't use the Add-ADPermission cmdlet to configure Send As permissions. You must use the Add-RecipientPermission cmdlet.
The Send As permission is different than the Send on Behalf permission. If the user Chris has Send on Behalf permission on Michelle's mailbox, when Chris sends an e-mail as Michelle, the From address shows Chris on behalf of Michelle. Microsoft Outlook users can configure Send on Behalf permissions on their own mailbox using delegates. Administrators can configure Send on Behalf permissions on any recipient type using the GrantSendOnBehalfTo parameter.
Also, before you perform this procedure, be aware that you cannot send e-mail messages on behalf of a mailbox if the mailbox is hidden from address lists. When sending a message, Exchange requires that an e-mail address is resolved in the From field. In the case where a message is sent on behalf of a mailbox that is hidden from address lists, the SMTP address is interpreted as an address that isn't from your organization (known as a foreign address) and is rejected.
Give a tenant user Send As
permission - as run by a tenant administrator
This example allows a tenant administrator to give a tenant user Send As permission because it is run within the tenant organization, the tenant administrator doesn't need to specify the organization. This example gives the tenant user named Ayla Kol Send As permission for the Help Desk mailbox , run the following command:

Add-RecipientPermission "Help Desk" -AccessRights SendAs -Trustee "Ayla Kol" |

Ayla can now send messages that appear to come directly from the Help Desk mailbox.
Note By default, you are asked
to confirm the addition of the Send As permission. To skip the
confirmation prompt, use -Confirm:$false.
