Notification E-Mails - HTML design broken with Outlook and large logo pic

Update #2: (possible solution)

So i’ve been trying around with the Conditional Comments (<!--[if mso]> statement) and
was able to optimize the presentation of the uploaded XWiki Logo in MS Outlook 2016 (on Windows 10).

Here is the result of an notification E-Mail with my fix approach inside XWiki.Notifications.MailTemplate, it compares the the same message in Mozilla Thunderbird and Microsoft Outlook 2016 (both on Windows 10):


  • So this should solve the problem if someone is using a large picture for his XWiki instance logo.

Here is the source code which i’ve used (probably it can be enchanced a litte bit):

  <table style="max-width: 570px; margin:0 auto" cellspacing="0" cellpadding="0" width="100%" align="center"><tr><td>
    ## Logo table
    <table width="100%" border="0"><tr height="55px">

      ## Display a table of content
      #displayTOC($sortedEvents)
      ## Display Events
      #foreach ($list in $sortedEvents.values())
        #foreach ($sortedEvent in $list)
          #displaySortedEvent($sortedEvent)
        #end
      #end
    ## End of the events div
    </div>
  ## End of the main table
  </td></tr></table>
## End of the main div
</div>

Maybe this could be included into the official XWiki.Notifications.MailTemplate?

Hope this helps!
