Outlook 2016 Plugin for Windows

Apologies if this is on another thread, but I can't seem to find it...

Is there an Outlook 2016 plugin in the works at all? I can see download links in my Setup page for 2007, 2010 and 2013 (and then MAC 2016), but nothing for Windows Outlook 2016.

Specifically, I'm IMAP if that makes a difference.

Thanks,

Steve
