I have an anoying problem with Outlook 2013. My inbox is flagged with "1" unread message, but this is not the case. Even when I empty my inbox folder, this bold "1" stays next to my folder new as it contains a new message.

I've tried to "empty" it, to "clean" it, to "mark all as read" it. Nothing works.

Any tips?

outlook.exe /cleanviews

This cleans the internal viewstate and should resolve the problem.

Worked for me. Far better than marking everything as read which is counter productive! –  Quango Mar 26 at 9:49
Cleared out the phantom unread emails in my folders however my inbox still showing 8 unread and empty –  snafu918 Jun 6 at 23:58

on a microsoft forum they said to go to start>run>type outlook/cleanips but it says no such command so i navigated in cmd to C:\Program Files (x86)\Microsoft Office\Office15> and typed there outlook/cleanips (but close outlook first) and voila it worked.

I haven't tried the "outlook.exe /cleanviews" command, but I fixed my Outlook by disabling Cached Exchange Mode and then re-enabling it.

You can set it under your Account Settings. There's an option of "Use Cached Exchange Mode"

I've managed to fix this by going to the web access, right-clicking the problematic folders and selecting "mark all as read". After this, Outlook stopped displaying wrong unread messages count.

Similar to the answer provided by @Maged, you can do the following:

  1. Close Outlook
  2. In a command-prompt, go to one of these directories (whichever one has outlook.exe):

    a. C:\Program Files\Microsoft Office\Office15

    b. C:\Program Files (x86)\Microsoft Office\Office15

  3. Run "outlook/cleanips".
