ANSWER 1

Score 73

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.

ANSWER 2

Run

outlook.exe /cleanviews

This cleans the internal viewstate and should resolve the problem.

WARNING: Running this command will also reset any custom views!

ANSWER 3

I tried "marked all as read" at first and it did not work so I disabled the "Use Cache Exchange Mode" then "marked all as read" and bingo!

I later re-enabled "Use Cache Exchange Mode"

ANSWER 4

Score 7

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"
