Skype for Business shows missed conversation notification while it does not list any

Question

For a long time, Skype for Business has been showing a “You have 1 missed conversation(s)” notification like this:

However I don't have any missed conversation when I scroll the list of conversations below it.

How do I make this notification disappear?

Answer 1

Click the “View More in Outlook…” link at the bottom of the screen to access the complete list of conversations.

Ensure all conversations are marked as read. After a moment, Skype for Business will remove the notification.
