I have a user with 2 MS exchange 2010 accounts (Both on the same server but wanted them separate to be able to send emails from another account) &nbsp;Anyway i keep rebuilding his profile but after a while the same thing happens. &nbsp;He has many folders and sub folders but sometimes he just logs into his outlook and some of his folders either don't show up or the emails under it are missing. &nbsp;Not sure how to fix the issue. &nbsp;Sometimes when you do send and receive it comes up with a error about not being able to access his ost file. &nbsp;It is just the one user i have 7 more setup just like him in the office but his is the only one having the issue. &nbsp;I found a article about uninstalling a sept 2013 update from his pc but he doesnt have it. &nbsp;I need a way to fix this once and for all user is getting frustrated.
