Exchange EWS issue convert ID

Question

I am trying to extend some intergration between oracle apex and exchange.

I would like a link in an apex application that can launch a OWA webmail window.

I have got oracle connected up with EWS and can read through an inbox, But seems I need to convert the EWS ID that EWS provides into a OWA ID.

Something is wrong - likely me - but really could do with some support to get this working.

I have followed the example:

https://docs.microsoft.com/en-us/exchange/client-developer/web-service-reference/convertid-operation#convertid-operation-error-response-example

But I am getting an error back "ErrorInvalidIdMalformed"

or " EWS for PL/SQL: ErrorInvalidIdMalformed: This id is of the wrong type for this conversion operation (mailbox id vs. public folder id)."

what am I doing wrong here?

Here is my request:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">

    <t:RequestServerVersion Version="Exchange2013"/>
  </soap:Header>
  <soap:Body>
    <ConvertId xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"
               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"
               DestinationFormat="OwaId">
      <SourceIds>
        <t:AlternateId Format="EwsId" Id="aaa"
                       Mailbox="[e-mail]"/>
      </SourceIds>
    </ConvertId>
  </soap:Body>
</soap:Envelope>

EWSId's are base64 so they are case sensitive a common mistake is for people to ignore this, you probably need to post one of the Id's that is malformed as that would give us a better indication of what is happening. However instead of using convertId why dont you just use https://docs.microsoft.com/en-us/dotnet/api/microsoft.exchange.webservices.data.item.webclientreadformquerystring?view=exchange-ews-api
