Automatic redirection of Exchange ActiveSync On-Pre

Hi evandromalmsteen 

When Moving from Exchange OnPrem to Exchange Online the Autodiscover Request is answered with a RedirectAddr Attribute.

After the Cutover the Mailbox has set a TargetAddress Attribute. This Email Adress will be given back via Autodiscover to the Active Sync Client.

Now it depends on the Active Sync Client if he "understands" what to do and to do a Autodiscover Request against the Emailaddress received by the RedirectAddr Attribute.

<?xml version="1.0" encoding="utf-8"?>

<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">

    <Response xmlns="http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a">

        <Account>

            <Action>redirectAddr</Action>

            <RedirectAddr>email address removed for privacy reasons</RedirectAddr>

        </Account>

    </Response>

</Autodiscover>

Kind Regards
Andres
