Updating the global address list
Apparently this caused Outlook to delite the list of cached email adresses?? If you login to OWA you will see the GAL - that uses live information.
Therefore this is really 2 questions: 1) Why does the GAL not updating? Therefore the first thing you need to do is check whether changes to user accounts are seen through OWA. Go to Organization Configuration, and then click Mailbox. Right click the appropriate database and go to Properties 4. First of all I dont see any entries in the ewent viewer what so ever regarding any issues related to OAB or a like.
Using cmdlets like those below will save you time, more so when you realize that every Exchange 2007 configuration task has a faster command-line equivalent.
Furthermore, certain commands are ONLY available in the Shell, for example, new-Global Address List.
Until you can see all of the information in OWA, don't think anything is going to change on the clients. Choosing the option to Download the Address book should have had no effect on the nickname files. If I access Outlook 2010 I see the full internal address list (GAL??I have never seen the entries lost by doing what you posted. All Users is the live information, therefore if you aren't seeing the information elsewhere, then the OAB isn't updating correctly. ) except that this is not updated and missing newly created users.Therefore that must have been caused by something else.
