A mailbox store may not update content indexing scheduling information during an update from the directory service.
The mailbox store returns the globally unique identifier (GUID) of an object based on different types ofinformation (NTDN, SMTP proxy, LegacyDN, and so on). All of these functions expect the objects to have a mailbox GUID to return failures; this problem can occur if the objects do not have one.
The scheduling occurs in the background, based on timed events. This can result in an inability to process a timed event for a Messaging Database (MDB), which disables background event processing on that MDB until the next mailbox store recycle.
