Office365 – At give send on behalf rettigheder til en bruger.

If you need to give Send As Permissions to a User in Office 365, it can be done using a few simple commands in Exchange Online PowerShell.

Send As permission is used when you need to give a user permission to use another recipient’s email address in the From address.

First connect to your Office 365 tenant, using Windows PowerShell.

To connect to Exchange Online, just start a PowerShell session and type in following commands:

$Cred = Get-Credential

 

The above command prompts you, for your Office 365 tenant admin credentials, it is important to enter as UPN format, such as e.g. admin@contoso.onmicrosoft.com.

Next, we will create a new remote PowerShell session using the following cmdlet:

$s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic –AllowRedirection

Next we import of the PowerShell session:

Import-PSSession $s

 

You are now connected to Exchange Online with you Office 365 Tenant admin and can use Exchange Online PowerShell cmdlets available.

Next grant a user permission to access another user’s mailbox, so they have permission to open it:

Add-MailboxPermission <mailbox> -User <user or security group> -AccessRights FullAccess

Then give Send As permission to users, som they can send as the user:

Add-RecipientPermission <identity> -AccessRights SendAs -Trustee <user>
