+In Outlook 2016, you can't setup an account from an Exchange 2007 server without
+having autodiscover setup correctly. The *Manual Setup* only offers "Exchange
+ActiveSync" which doesn't work with the 2007 Exchange. (The working method is
+named "Microsoft Exchange".)
+
+Usually, for an email address `account@example.org`, Outlook 2016 will look for
+`https://autodiscover.example.org/autodiscover/autodiscover.xml`. If that DNS
+entry isn't configured or there's no `autodiscover.xml` at that address, the
+account setup in Outlook will fail.
+
+However, there are [a few ways](https://www.howto-outlook.com/howto/autodiscoverconfiguration.htm)
+to override where Outlook is looking for that XML. The probably easiest one is
+by adding a registry key to point to a local file containing the actual path to
+the desired `autodiscover.xml`.
+
+So, let's say, you can reach OWA via `https://mail.example.org/owa/`, then the
+`autodiscover.xml` is `https://mail.example.org/autodiscover/autodiscover.xml`.
+
+And you're trying to add an email address `john@company.com` which is managed by
+that Exchange 2007 (and you can login to OWA just fine).
+
+1. Create a file `C:\autodiscover.xml` with the following contents:
+
+        <?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>
+              <AccountType>email</AccountType>
+              <Action>redirectUrl</Action>
+              <RedirectUrl>https://mail.example.org/autodiscover/autodiscover.xml</RedirectUrl>
+            </Account>
+          </Response>
+        </Autodiscover>
+
+2. Open **regedit** and navigate to the path `HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\AutoDiscover`
+3. Add a new *String* (REG_SZ), name it `company.com` (the part after the `@` in your
+   mail address) and assign the value `C:\autodiscover.xml` to it.
+4. Done. Now open Outlook 2016 and add your account. It should work now.
