Granting SendAs right to a group

Create a distribution list called CRM Users containing two Exchange users who also use Sage CRM. The user email addresses in the example below are ebdenm@panoply-tech.com and mayes@panoply-tech.com.
Copy
```
New-DistributionGroup -Name "CRM Users" -IgnoreNamingPolicy "ebdenm@panoply-tech.com","mayes@panoply-tech.com" |
%{ Add-DistributionGroupMember -Identity "CRM Users" -Member $_ }
```
Run the following command to list the members of the distribution group:
Copy
```
Get-DistributionGroupMember "CRM Users"
```
This returns the members:
Name RecipientType
--- -------------
ebdenm UserMailbox
mayes UserMailbox
Send the members of the distribution group to the Get-Mailbox command and forward the array of resolved mailboxes to the Add-MailboxPermission cmdlet. The mailbox for the Sage CRM SMTP user is crmuser@panoply-tech.com:
Copy
```
Get-DistributionGroupMember "CRM Users" | Get-Mailbox | Add-MailboxPermission -User crmuser@panoply-tech.com -AccessRights FullAccess
```

Set the SendAs permissions:

Get-DistributionGroupMember "CRM Users" | Get-Mailbox | Add-RecipientPermission -AccessRights SendAs -Trustee crmuser@panoply-tech.com
