<h2 class="wp-block-heading">Checking First:</h2>



<p>You&#8217;ll need to provide two things to get this code working, First the Source account that will need access to the mailboxes. in this case referred to as &#8220;ServiceAccount&#8221;. </p>



<p>CSV List of Mailbxoes:</p>



<p>You&#8217;ll need to provide list of Mailboxes of the users you&#8217;d like to provide access to, the List must be user&#8217;s Identity either UPN or SMTP would be fine. </p>

<p>The Service account&#8217;s Identity must be the UPN attribute. </p>



<p>If you would like to improve this code please do comment or get in touch directly</p>
