Windows 10: Outlook 2010 Mark All As Read Error

I just bought a new Windows 10 machine (HP Envy) and I'm running Outlook 2010. When I select multiple e-mails (Shift, select top e-mail, select bottom e-mail) it correctly highlights all e-mails. Then when I right click and select "Mark as Read" it removes the highlight from multiple e-mails and instead only highlights the last e-mail. I would often select multiple e-mails, mark as read, and then delete.

It's not a huge deal, but I could do this in Outlook 2010 in Windows 8.1 without issue and I can do it in Outlook 2003. Any ideas?

E-mail read and deleted on WP7 shows up in in Outlook in Deleted folder but displays as unread

It also happens in Windows Phone 8 with Exchange 2010, any e-mail I read on the phone is not marked as read in outlook

 

How do I mark all emails as read?

That's strange - I see this option - what options do you have? Is this in the standard Messaging program rather than the HTC Touch Flo interface?

There's no way I'm the only person experiencing this problem. Has anyone else seen it?
