unwillingToPerform is a server error. The Active Directory server (which I¹m
assuming you¹re using with your Exchange account) has some strict
requirements on what it will do, especially with Virtual List View (VLV),
which requires some very particular indexing strategies in order to get
right.
It would be interesting to figure out what particular query is being sent
that AD is responding negatively to.
Entourage performs several queries against the LDAP server when first
connecting to determine configuration settings to use, and thereafter either
is in a browsing (VLV) mode or a non-browsing/query-only (non-VLV) mode.
Does this error happen during e-mail addressing, or when browsing the GAL?
In the latter case, is it the first time you try to browse the GAL or during
subsequent times? Or after changing your Network Location? or?
Thanks in advance,
