When one of my users checks her Outlook 2010 Inbox, just occassionally, she will see that one of the emails is duplicated in the list of emails in the Inbox.
However, when she clicks on it, a different email opens up. This appears to be because this is possibly caused by a screen memory issue. I appear to be able to prove this by scrolling the email(s) out of the view, and then back again, effectively doing a screen redraw for the Outlook part of the screen. The duplicate will then disappear and everything will look normal.
So something is causing duplication, fake or otherwise, but no one else seems to get this problem, and I’ve never seen it. What can be done about it?
