Outlook 2013 Unread Email Count Incorrect (missing) on Folders

My Outlook 2013 for some reason stopped showing the count of unread emails in each folder, for the folders on the corporate Exchange server. Local archive/PST folders were fine. How does someone fix this problem?

Solution 1:

I used a combination of the suggestions listed in this SuperUser post.

For me the following steps worked.

1. In Outlook - Go to File | Account Settings, then "Account Settings in the drop down".
2. Select the "Data Files" tab.
3. Select your account/location in the displayed list and click the "Settings..." tool button.
4. In the displayed dialog select the "Advanced" tab.
5. Uncheck "Use Cached Exchange Mode".
6. Click "OK".

If you close and reopen Outlook now it may work, if it doesn't continue reading:

7. Close Outlook.
8. Start Outlook using "/cleanips". I have 32-bit Outlook so this is where it was on my system.

"C:\Program Files (x86)\Microsoft Office\Office15\OUTLOOK.EXE"/cleanips

9. After Outlook starts. Use the above instructions to go turn "Use Cached Exchange Mode" back on again and quit Outlook. Then start Outlook again with "/cleanips".

"C:\Program Files (x86)\Microsoft Office\Office15\OUTLOOK.EXE"/cleanips

After doing this the unread email counts for each Exchange folder should display again.

Solution 2:

Zolt mentioned in Microsoft Answer forums to try and 'disable hardware acceleration' under the Display options for Outlook.
