We use addressbook policies on out exchange 2010 server. So we have multiple GAL's. Each GAL has a filter based on the customattribute1 value. For each department there is a GAL. And each user in a department has an addressbook policy set which contains the corresponding GAL.
We have a user which has a addresbook policy set for department A. Department A contains 10 users.
When we configure outlook for that user, the GAL contents aren't what we expect. It contains al the adresses on the exchange server.
