When populating Mail or Calendar Synchronization collection via LDAP filter it may display the projected membership in the Preview dialogue correctly while still process or not process some mailboxes on the agent level. En example would be (!(isCriticalSystemObject=TRUE)) exclusion LDAP filter which filters out any special accounts like Administrator, where this filter will still be ignored and Administrator account processed by the agent while Preview would NOT list Administrator mailbox. Why is there such discrepancy?
If Associated Domain Controller configured for the current Exchange server also hosts GC copy, agent will connect via port 3268 and will be using Global Catalogue for collection enumeration. Some attributes like isCriticalSystemObject are not replicated to GC by default causing LDAP filter to work incorrectly.
This inconsistency will be fixed in the future QMM versions and Preview dialogue will be using the same logic as agent does during the collection population. When constructing LDAP filter for Mail or Calendar sync collections please test it against GC and ensure all required attributes are replicated to GC.
