I have a user with Outlook 2010 and he has folder with one subfolder in it, and it seems to have duplicated itself infinitely.

(Project --> Sub-Project --> Project --> Sub-Project) and on and on. There is a hand icon on the folder like it is shared but it doesnt appear to be and it cant be deleted. I get an error message becuase there are over 4000 items which is an Outlook limitation.

Ive also noticed that I cant run Outlook in cached mode. The error that pops is because of running out of resources. I assume this is because of the infinite folders.

How can I get rid of these. We are running against Exchange 2010.
