AddDelegate Operation

The following example of an AddDelegate request shows an attempt to give user1 delegate permissions on folders that are owned by user2. User1 is given Author-level permissions to user2's Calendar folder and Reviewer-level permissions to user2's Contacts folder. User1 will not receive copies of meeting messages and will be unable to view private items in user2's mailbox. Meeting requests will be sent to both user1 and user2.

The following example shows the response to a request to add a delegate who has already been added to the principal's mailbox.

      <m:ResponseMessages>
        <m:DelegateUserResponseMessageType ResponseClass="Error">
          <m:MessageText>The user is already a delegate for the mailbox.</m:MessageText>
          <m:ResponseCode>ErrorDelegateAlreadyExists</m:ResponseCode>
          <m:DescriptiveLinkKey>0</m:DescriptiveLinkKey>
        </m:DelegateUserResponseMessageType>
      </m:ResponseMessages>
      </m:AddDelegateResponse>
  </soap:Body>
</soap:Envelope>

If the ErrorDelegateAlreadyExists response code is returned when you try to add a delegate, use the GetDelegate Operation to get all the current permissions for the delegate, and then use the UpdateDelegate Operation to set the new permissions.
