Hi,

We have recently been told that a lot of the systemmailboxes are missing
from our mail stores.
So, we followed the instruction on TechNet to recreate them 1 week ago.
Now we are getting a weird problem and not sure where it is related to the
systemailboxes.

Some of our staffs are having problems deleting some of their e-mails on
their inbox. (not all of them.. just randomly 1 or 2 per days)
I actually checked all permission settings and they look just fine.
If I grant myself permission with Full control on those people's mailboxes,
I can delete those undeletable e-mails.
So, I tried to explicitly grant Full control to those users on their
respective mailboxes.
However they still can't delete those trouble e-mails.

Any idea / solution is much appreciated.
