Question

Your rewrite rule is just redirecting to the same domain. So if a user enters just domain.com (defaulting to http) it will redirect to https://domain.com. If your SSL certificate does not contain domain.com but only www.domain.com it will cause the browser to prompt a warning about a wrong certificate. Though most certificate authorities nowadays issue certificates with both the domain with and without www (but maybe yours not).

If you want the user to always use https://www.domain.com (always with www) you should use the following rewrite rule:

<rule name="Force HTTPS" stopProcessing="true">
    <match url="(.*)" />
    <conditions logicalGrouping="MatchAll">
        <add input="{HTTPS}" negate="true" pattern="^ON$" />
        <add input="{HTTP_HOST}" negate="true" pattern="^www\.domain\.com$" />
    </conditions>
    <action type="Redirect" url="https://www.domain.com{REQUEST_URI}" appendQueryString="false" redirectType="Permanent" />
</rule>

It will force SSL and will force www.domain.com as a host header. If not, it will issue a permanent redirect (= beter) to the same URL.
