This is great for testing or when it is important that changes are published immediately (note that users must still update the OAB manually or wait a OAB sync interval to see the changes).The overall process is basically the same as what Office Communications Server does, but with added flexibility of easily customizing some of the timing of the different events.This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.Even though Outlook is the last in the chain, it is often the first level where the troubleshooting takes place as usually this is where the request is coming from.The event itself happens the next time abserver looks to see if a sync event has been triggered.
