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.The entire process happens over time based on a number of intervals, and by default looks like this: value indicates the default behavior of Lync Server to search Active Directory for any changes every minute.
This polling interval is 5 minutes by default and can be customized to any value between 5 seconds and 3 hours.
Because Step #1 in the process happens by default every minute then any recent changes in AD should already be imported into the SQL database.
As a learning progression, by all means start with GUI Exchange Management Console, but note as each Wizard completes so it shows you the corresponding Power Shell commands.
Why not save these so that in future you can use the cmdlets in the Shell?
However, be careful, don't create too many lists, and furthermore, give thought to meaningful names for your lists.
The situation, you want to modify the GAL, however, you discover that you cannot edit (or delete) the Default Global Address List.Number of stale device files deleted: 0 Number of device full files written: 1 with 0 total contacts Number of device delta files written: 11 with a total of 0 new/updated contacts and 0 deleted contacts.Number of device bytes written: 1,657 compressed to 1,248 bytes on disk.The first step only needs to be performed once per workstation, while the second would be done each time a forced update is desired.Take note that the there is another difference here between the Lync and Communicator clients.If this is not the case or for some reason normal replication is failing then a manual process can be used to toss out the entire copy of AD information in the SQL database’s address book store and regenerate a completely new copy.
