These are the same permissions.

They are the same permission, but they were applied to two different people through different interfaces. &nbsp;So, will both Jane and John have Send On Behalf Of permission? &nbsp;Or will the Exchange permission overwrite the permission configured on the Outlook client?<br />
<br />
I ask because people had been granted SOBO permission to a mailbox through the Outlook client. &nbsp;However, when I granted someone else SOBO permission through Exchange, the original people ceased to have SOBO. &nbsp;I found this odd, which led me to believe that permissions applied to a mailbox through Exchange overwrite permissions applied through the Outlook client.

Hi, everyone. &nbsp;Newbie to Exchange Administration...<br />
<br />
I have noticed that Send On Behalf Permission can be set on the Outlook client or through the Exchange server. &nbsp;Are permissions set through each location cumulative?<br />
<br />
For example, if I grant Jane Doe Send On Behalf Of permission to my mailbox through the Outlook client, then grant John Smith Send On Behalf Of permission through Exchange PowerShell, will both Jane and John have Send On Behalf permission? &nbsp;If not, which takes precedence?<br />
<br />
Thank you for your thoughts on the matter.
