How to give Users Send as Permission in Office 365 using PowerShell

Posted under Office 365 by ifoundafix


The other day I Found A Fix for a recent problem I was having. The issue is described as follows;

I needed to be able to give myself send as access to another users mailboxes on Microsoft Office 365

To do this I found the following steps were required.

Note: Powershell commands are in bold. Type enter after each line item.

1. Install remaining script-lets so you’ll need to install the PowerShell from this link

2. Run Powershell as administrator.

3. Login to Office 365 with $cred=Get-Credential

4. Enter the admin username and password i.e name@mydomain.com and password.


Set-ExecutionPolicy Unrestricted

Now to Give permission to other users Mailboxes

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

Import-PSSession $Session

To give Bob permission to Send as John

Add-RecipientPermission bob@pctechnix.ie -AccessRights SendAs -Trustee john@pctechnix.ie

To finish, enter Y and hit return.

I hope you too have found a fix.
