Hi, received an automatic update for my Windows 10 a couple of days ago and since then my PC has been sounding the notifications sound (as if I'm receiving a new email) every minute or so without actually reporting any new notifications or new emails. I've unplugged all externally connected devices (in case it was a device issue) and have found that the only way it stops is if I close Outlook (2016). I usually leave my Outlook open so I know when new emails arrive - but as it's sounding notifications for no apparent reason I've just closed it down to get some peace. I've even tried setting the notifications sound to 'none' for Outlook in the Notifications / All Settings / System / Notifcations & Actions tab - and yet it still sounds a false notification when Outlook is open. I'd be grateful for any help anyone could offer on this - it's driving me crazy! Thanks
