Problem:
Outlook 2010 contains folders into which all my e-mail is put. My original order was designed to be alphabetical by folder name. Now in the folders list they’re no longer sorted alphabetically.
What setting will permanently correct this so that the folders remain sorted alphabetically at all times?

Solution:

you may try the below steps:

start> run> enter the below command without quotes
“outlook /resetnavpane”
ok

Have fun!
