"Access denied" error when doing user profile offline sync

We are using Vista in our company, everyone's home folder (h: drive) i
having offline sync enabled on it and hence my home folder will b
copied to the computer that I logged in with my account. This is not
big issue for me as I understood this is what supposed to be happening

But I just got a wierd problem of Vista offline sync
One day I logged in to an user's machine to help him fix a problem an
I logged off after the job done. After a few days I got an email fro
that user with attached a screenshot of some offline sync errors on hi
machine
The error said my profile on his machine is generating errors below
-Offline Files "Access Denied"
-Sync failed with Offline File

It looks like that my profile left on his machine is still trying to d
the sync even when the user is logged in with his account
Has anyone seen this problem before

I don't understand why this is happening as I though the offline syn
of my profile (H: drive) only happens when I am logged in

Any advice would be much appreciated
