Same issue. Unread emails in inbox do not show in the count. When Outlook 2013 starts they show briefly in the folder pane then disappear.
Right click/Properties on Inbox folder shows no counts whether unread or total is selected
Clicking Unread at the top does not yield any additional messages on server
Going into OWA shows correct unread count, but as suggested by some does not fix Outlook 2013
Running outlook.exe /cleanviews as suggested by some does not work
Disabling cached exchange mode shows the correct number of unread emails
Running scanpst.exe on the .ost file is a brief fix (one day)
I also use the Exchange account on my iOS iPhone 5S. It shows the correct unread account.
Starting in safe mode shows the correct number of unread emails
I disabled ALL the Add-Ins, restarted and the Inbox (and other folders) started showing correct unread count. I turned each Add-In back on until I found the one that erased the unread count. I keep that one disabled since it got installed by
another program and I don't need it. This is a repeatable fix, but only time will tell if it comes back.
