His Royal Dryness, The Duke of Cork

 I had an annoying message in Outlook 365 which appeared every day saying "Take Outlook Anywhere.  Stay connected to what matters.  Get Started (or Get it Now)"  There appears to be no way of stopping this appearing through the user interface, although you can just close it.  The reminder seems to appear every day  Even after a bit of searching online, I couldn't really see any obvious, clear solutions.  I even found some post suggesting that you need to complete on online form to opt out.  As far as I could tell this was just a data-harvesting scam.  This is what I pieced together to get rid of it. Open Regedit (Start --> Run --> Regedit) You then need to navigate to this node Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\TargetedMessagingService\MessageData\ Right-Click MessageData and choose "Find" Type 425141231 (I got this value by clicking get started and taking it from the URL) You should find a node ending in BizBar with sub node
