Hidden Users will randomly show back up in the GAL

Running a Single Exchange 2007 Ver. 8.03.0083.000 using all roles.

Database size > 100 users.

After disabling an account and hiding it from the Exchange Address Lists, it will sometimes randomly clear the attribute and show back up in the GAL months later. We have had users show back up and looking at the mailbox properties the "Hide from Exchange Address List" box is not checked. I am the only one administering the server and this has happened to some mailboxes several times.

Applying the settings again do remove the account from the OAB, and the GAL, so they are updating fine. Then at random, as sometimes its a couple weeks, or a couple months, or even six months, a few disabled users will show back up and I have to re-check the Hide box.

Any ideas?

    This is indeed very strange behavior. Have you tried installing the latest service pack?

    The goal is to prevent the behavior. Re-hiding the users are easy. I know I am on SP3 at least as far as version goes.

    Hi Hendrk,

    Yes I have, but this problem seems to have disappeared. It's been a while now since a user has popped back in.

    This phenomenon has disappeared and if it returns I will re-submit with more information.
