we have had some contacts in our internal directory which have been removed. however when composing new emails in outlook, i can still see them as suggestions, which is okay since they are cached.
however, when i am in owa, i can still see them. when i start to type the name of the person i can see their "contacts" email address come up, which have been deleted previously. once i click on search contacts and directory, i see the correct email address come up.
question is where are the contacts cached in owa? and how can i get rid of them? if they are on the server, maybe i can remove them for all users, which i doubt would be the case.
